D. PETRAEA (syn D. rupestris).—Rock Daphne. Tyrol. This is quite hardy in the more sheltered corners of the rock garden, with neat, shining foliage and pretty rosy flowers, produced so thickly all over the plant as almost to hide the foliage from view. At Kew it thrives well in peaty loam and limestone, and although it does not increase very quickly is yet happy and contented. It is a charming rock shrub.

D. PONTICA.—Pontic Daphne. Asia Minor, 1759. This is much like D. lauriola, but has shorter and more oval leaves, and the flowers, instead of being borne in fives like that species, are produced in pairs. They are also of a richer yellow, and more sweetly scented.

D. SERICEA (syn D. collina).—Italy and Asia Minor, 1820. This forms a bush fully 2 feet high, with evergreen, oblong, shining leaves, and clusters of rose-coloured flowers that are pleasantly scented. It is quite hardy, and an interesting species that is well worthy of more extended culture. There is a variety of this with broader foliage than the species, and named D. sericea latifolia (syn D. collina latifolia).

DAPHNIPHYLLUM.

DAPHNIPHYLLUM GLAUCESCENS.—East Indies, Java and Corea. A handsome Japanese shrub that will be valued for its neat Rhododendron-like foliage, compact habit of growth, and for the conspicuous bark which is of a warm reddish hue. The leaves are large and elliptic, six inches long, and are rendered strangely conspicuous from the foot-stalks and midrib being dull crimson, this affording a striking contrast to the delicate green of the leaves. It grows freely in light sandy peat. There are two well-marked forms, one named D. glaucescens viridis, in which the red markings of the leaves are absent; and D. glaucescens jezoensis, a pretty and uncommon variety.

DESFONTAINEA.

DESFONTAINEA SPINOSA.—Andes from Chili to New Grenada, 1853. This is a desirable shrub, and one that is perfectly hardy in most parts of the country. It is a charming shrub of bold, bushy habit, with prickly holly-like foliage, and scarlet and yellow, trumpet-shaped pendent flowers, borne in quantity. The shelter of a wall favours the growth and flowering of this handsome shrub, but it also succeeds well in the open if planted in rich, light soil, and in positions that are not exposed to cold and cutting winds.

DEUTZIA.

DEUTZIA CRENATA (syn D. scabra and D. Fortunei).—Japan 1863. This is of stout, bushy growth, often reaching a height of 8 feet, and lateral spread of nearly as much. The ovate-lanceolate leaves are rough to the touch, and its slender, but wiry stems, are wreathed for a considerable distance along with racemes of pure white flowers. It is a very distinct shrub, of noble port, and when in full flower is certainly one of the most ornamental of hardy shrubs. The double-flowered form, D. crenata flore-pleno, is one of the prettiest flowering shrubs in cultivation, the wealth of double flowers, not white as in the species, but tinged with reddish-purple being highly attractive. D. crenata, Pride of Rochester, is another form with double-white flowers, and a most distinct and beautiful shrub. Two other very beautiful varieties are those known as D. crenata Watererii and D. crenata Wellsii.

D. GRACILIS is a somewhat tender shrub of fully 18 inches high, with smooth leaves and pure-white flowers produced in the greatest freedom. It does well in warm, sheltered sites, but is most frequently seen as a greenhouse plant. A native of Japan.

DIERVILLA.

DIERVILLA FLORIBUNDA (syn D. multiflora and Weigelia floribunda), from Japan, 1864, has narrow, tubular, purplish-coloured corollas, that are only slightly opened out at the mouth. The Diervillas are valuable decorative shrubs, of free growth in good rich loam, and bearing a great abundance of the showiest of flowers. For shrubbery planting they must ever rank high, the beautiful flowers and rich green ample leafage rendering them distinct and attractive.

D. GRANDIFLORA (syn D. amabilis and Weigelia amabilis).—Japan. This is of larger growth than D. rosea, with strongly reticulated leaves, that are prominently veined on the under sides, and much larger, almost white flowers. It is a distinct and worthy species. There are some beautiful varieties of this species, named Isolinae, Van Houttei, and Striata.

D. ROSEA (syn Weigelia rosea).—China, 1844. This is a handsome hardy shrub of small stature, with ovate-lanceolate leaves, and clusters of showy pink, or sometimes white flowers, that are produced in April and May. There are many good varieties of this shrub, of which the following are the most popular:—D. rosea arborescens grandiflora; D. rosea Lavallii, with an abundance of crimson-red flowers; D. rosea Stelzneri, with an abundance of deep red flowers; D. rosea hortensis nivea, large foliage, and large, pure-white flowers; D. rosea candida, much like the latter, but bearing pure-white flowers; and D. rosea Looymansii aurea has beautiful golden leaves.

DISCARIA.

DISCARIA LONGISPINA.—This is at once a curious and beautiful shrub, of low, creeping growth, and poorly furnished with leaves, which, however, are amply made up for by the deep green of the shoots and stems, and which give to the plant almost the appearance of an evergreen. The flowers, which are bell-shaped and white, are almost lavishly produced, and as they last for a very long time, with only the pure white assuming a pinky tinge when subjected to excessive sunshine, the value of the shrub is still further enhanced. For planting against a mound of rock this scrambling shrub is of value, but the position should not be exposed to cold winds, for the plant is somewhat tender. From South America, and allied to the better known Colletias.

D. SERRATIFOLIA (syn Colletia serratifolia), is even a handsomer plant than the former, with minute serrated foliage, and sheets of small white flowers in June.

DIOSPYROS.

DIOSPYROS KAKI COSTATA.—The Date Plum. China, 1789. Fruit as big as a small apple; leaves leathery, entire, and broadly ovate; flowers and fruits in this country when afforded the protection of a wall. The fruit is superior to that of D. virginiana (Persimmon).

D. LOTUS, the common Date Plum, is a European species, with purplish flowers, and oblong leaves that are reddish on the under sides. Both species want a light, warm soil, and sheltered situation.

D. VIRGINIANA.—The Persimmon, or Virginian Date Plum. North America, 1629. A small-growing tree, with coriaceous leaves, and greenish-yellow flowers. In southern situations and by the seaside it is perfectly hardy, and succeeds well, but in other districts it is rather tender. The fruit is edible, yellow in colour, and about an inch in diameter.

DIRCA.

DIRCA PALUSTRIS.—Leather Wood. North America, 1750. A much-branched bush, of quite a tree-like character, but rarely more than 3 feet high. To the Daphnes it is nearly allied, and is close in resemblance; but there is a curious yellowish hue pervading the whole plant. The flowers are produced on the naked shoots in April, and are rendered conspicuous by reason of the pendent yellow stamens. They are borne in terminal clusters of three or four together. It delights to grow in a cool, moist soil, indeed it is only when so situated that the Leather Wood can be seen in a really thriving condition.

DRIMYS.

DRIMYS AROMATICA (syn Tasmannia aromatica).—Tasmanian Pepper Plant. Tasmania, 1843. This is, if we might say so, a more refined plant than D. Winteri, with smaller and narrower leaves, and smaller flowers. The plant, too, has altogether a faint reddish tinge, and is of upright growth. A native of Tasmania, and called by the natives the Pepper Plant, the fruit being used as a substitute for that condiment. Like the other species the present plant is only hardy in warm, maritime places, and when afforded the protection of a wall.

D. WINTERI (syn Winter a aromatica).—Winter's Bark. South America, 1827. The fine evergreen character is the chief attraction of this American shrub, so far at least as garden ornamentation is concerned. With some persons even the greenish-white flowers are held in esteem, and it cannot be denied that a well flowered plant has its own attractions. The long, narrow leaves are pale green above and glaucous beneath, and make the shrub of interest, both on account of their evergreen nature and brightness of tint. Unfortunately it is not very hardy, requiring even in southern England a sunny wall to do it justice.

ELAEAGNUS.

ELAEAGNUS ARGENTEA.—Silver Berry. North America, 1813. A spreading shrub 8 feet or 10 feet high, with lanceolate leaves clothed with silvery scales. The flowers are axillary and clustered, and are succeeded by pretty, silvery-ribbed berries.

E. GLABRA (syn E. reflexus).—From Japan. This is one of the handsomest species, forming bushes of delightful green, leathery leaves, and with a neat and rather compact habit of growth. It grows with great freedom when planted in light, sandy soil, big globose bushes being the result of a few years' growth. Being perfectly hardy it is to be recommended if only for the ample leathery, deep green foliage. The flowers are inconspicuous. There is a form having the leaves margined with pale yellow, and known under the name of E. glabra variegata.

E. LONGIPES (syn E. edulis and E. crisp a).—Japan, 1873. This species, is also worthy of culture, whether for the ornamental flowers or fruit. It is a shrub 6 feet high, bearing an abundance of spotted, oval red berries on long footstalks. Quite hardy.

E. MACROPHYLLA.—Japan. This is of robust growth, with handsome, dark green leaves, and purplish branch tips. The leaves are thick of texture, often fully 3 inches long, glossy-green above, and silvery beneath. The latter is all the more remarkable, as the leaves have the habit of curling up their edges, and thus revealing the light, silvery tint of the under sides. It thrives well in light, sandy peat, and may be relied upon as one of the hardiest of shrubs.

E. ROTUNDIFOLIA.—An interesting and perfectly hardy species, growing about five feet high, and remarkable for the great wealth of pretty scarlet and amber-coloured berries. The flowers are not very showy, but this is made up by the beautiful silvery leaves, most pronounced on the under sides, and wealth of fruit, which hangs on long stalks like Cherries.

Other species of less interest are E. pungens, of which there is a variegated variety; E. Simoni, a neat Chinese shrub; and E. latifolia, of good habit and with large leaves. The various species and varieties of Elaeagnus may all be cultivated in light, free soil, and from experiments that were recently made, they have been found of great value for planting by the seaside. They are popularly known as the Wild Olives and Evergreen Oleasters.

EMBOTHRIUM.

EMBOTHRIUM COCCINEUM.—Fire Bush. South America, 1851. This is a beautiful shrub, of tall growth, with flowers of great interest and beauty. Except in warm and favoured situations, it is not very hardy, and should always be grown as a wall plant. The fiery scarlet, orange-tinted flowers, resembling somewhat those of the Honeysuckle, are very beautiful by the first weeks of May. It grows to about 6 feet in height in southern England, and is, when in full flower, a shrub of unusual beauty.

EPHEDRA.

EPHEDRA VULGARIS (syn Ephedra monastachya), from Siberia, 1772, is a half-hardy shrub of trailing habit, with inconspicuous flowers. Thriving in very poor soil, or on rocky situations, is the only reason why it is introduced here.

EPIGAEA.

EPIGAEA REPENS.—Ground Laurel, or New England Mayflower. Northern United States, 1736. This is, perhaps, in so far as stature is concerned, hardly worthy of a place in our list, yet it is such a pretty and useful shrub, though rarely rising more than 6 inches from the ground, that we cannot well pass it over. For planting beneath Pine or other trees, where it can spread about at will, this prostrate shrub is most at home. There it enlivens the spot with its pretty evergreen foliage, and sweet-scented, white or pinky flowers. It is quite hardy.

ERCILLA.

ERCILLA SPICATA (syn Bridgesia spicata).—Chili, 1840. A small-growing, half-climbing shrub, with leathery, deep green leaves, and inconspicuous flowers. Hailing from Chili, it is not very hardy, but given the protection of a wall, or planted against a tree-stump, it soon forms a neat mass of evergreen foliage.

ERICA.

ERICA CARNEA.—South Europe, 1763. This is one of the most beautiful and desirable of hardy Heaths, on account of the richly-coloured flowers and early season at which they are produced. In the typical species the flowers are pink or flesh-coloured, and produced in January and February. It is a dwarf, compact growing species, with bright green foliage. There is a form with pure white flowers, named E. carnea alba, or E. herbacea, but although distinct and beautiful, it is not of so robust growth as the parent.

E. CILIARIS.—A pretty native species, with ciliate glandular leaves, and racemes of highly-coloured, rosy flowers. Found in Dorsetshire and Cornwall.

E. CINEREA,—Gray-leaved Heath. In this species, also a native of Britain, the flowers are of a reddish-purple colour, and borne in dense terminal racemes. There are numerous varieties, including a white-flowered E. cinerea alba; E. cinerea atro-purpurea, bearing dark purple flowers; E. cinerea atro-sanguinea, dark red flowers; E. cinerea coccinea, scarlet; E. cinerea purpurea, purple flowers; and E. cinerea rosea, with deep rose-coloured flowers.

E. MEDITERRANEA.—Mediterranean Heath. Portugal, 1648. This is a robust-growing species, of rather erect habit, and often attaining to fully a yard in height. Flowers abundantly produced, and of a pretty pinky hue. Of this there are several varieties, the following being best known: E. mediterranea hibernica, found in Ireland; E. mediterranea alba, with white flowers; E. mediterranea nana, of very dwarf growth; and E. mediterranea rubra, with showy, deep red flowers.

E. SCOPARIA and E. ERECTA are desirable species, the former bearing greenish flowers, and the latter of decidedly upright growth.

E. TETRALIX.—Cross-leaved Heath. A native species of low, and bushy growth, with close umbels or terminal clusters of pretty pinky flowers. The varieties of this most worthy of notice are E. Tetralix alba, white flowered; E. Tetralix Mackiana, crimson flowered; E. Tetralix rubra, deep red flowers; and E. Tetralixbicolor, with parti-coloured flowers.

E. VAGANS..—Cornish Heath. A native species, bearing pinky-white flowers, but there are forms with white and red flowers, named E. vagans alba and E. vagans rubra.

The various kinds of Heath succeed best either in peaty soil, or that composed for the greater part of light, sandy loam, but many will grow and flower freely if planted in rich yellow loam. They are very desirable plants, either for bed formation, for rockwork ornamentation, or for planting around the shrubbery margins. Propagation is effected either by cuttings or sub-divisions, but seedlings of several species spring up freely under favourable conditions.

ESCALLONIA.

ESCALLONIA FLORIBUNDA (syn E. montevideusis).—New Grenada, 1827. This is one of the handsomest species, bearing long, arching clusters of white flowers. It is a very desirable shrub for wall or lattice-work covering, against which it grows rapidly, and soon forms an object of great beauty by reason of its neat foliage and graceful habit, as also wealth of pretty flowers.

E. ILLINATA.—Chili, 1830. This should also be included, it being a handsome and pretty-flowered plant.

E. MACRANTHA.—Chiloe, 1848. This is a general favourite in English gardens, where it succeeds well, but especially in maritime parts of the country. It is of stout growth, 6 feet or more in height, of spreading habit, and with elliptical, serrulated, bright green leaves, and clusters of crimson-red flowers produced in summer. For wall-covering this is an almost invaluable shrub, although it succeeds well as a standard in all but the colder parts of the country. Any free, open soil suits it well, but thorough drainage must be attended to. There are several very distinct and good varieties, such as E. macrantha sanguinea, with flowers deeper in colour than those of the parent plant; and E. macrantha Ingrami, a profuse-blooming and very desirable form.

E. PHILLIPIANA.—Valdivia, 1873. When seen as a standard bush, and loaded with its myriads of tiny white flowers, this must rank amongst the handsomest members of the family. It is very hardy, and retains its foliage throughout the winter. The hybrid forms, E. exoniensis and E. leucantha, deserve recognition, the latter even as late as November being laden with its small spikes of pretty white flowers, which contrast nicely with the neat, evergreen foliage.

E. PTEROCLADON.—Patagonia, 1854. This is remarkable for the curiously-winged branches, which give to the shrub a rather peculiar and distinct appearance. The freely-produced flowers are white or pink.

E. RUBRA.—Chili, 1827. This has less handsome leaves and flowers than the above, but it is, all the same, a beautiful plant. The flowers vary a good deal in depth of colouring, and may be seen of all tints between pure white and red.

The Escallonias are all of very free growth in any light, warm, sandy, and well-drained soil, and are readily propagated.

EUCRYPHIA.

EUCRYPHIA PINNATIFOLIA.—Chili, 1880. This shrub, is as yet rare in cultivation, and is not suited for the colder or more exposed parts of the country. It is, however, a singularly distinct and beautiful shrub, with deep glossy-green, pinnate foliage, and bearing large, pure white flowers, that are rendered all the more conspicuous by the golden-yellow anthers. As an ornamental shrub it is well worthy of cultivation. In so far as its hardihood in this climate has to do, it may be mentioned that in various parts of England and Ireland it has stood in the open ground unharmed for several years back. Light, sandy, well drained peat would seem to meet with its requirements.

EUONYMUS.

EUONYMUS AMERICANA.—American Spindle Tree. North America, 1686. This is a deciduous or semi-evergreen shrub, of about 6 feet in height, found over a wide area in Canada and the United States. It is of partially erect growth, with long and lithe branches, covered with pleasing light green bark. Flowers appearing in June, and succeeded by rough, warted, brilliant scarlet capsules, which are particularly showy and attractive. It likes a shady situation, and rich, rather damp soil.

E. EUROPAEUS.—West Asia, Europe (Britain), &c. An indigenous species, rarely exceeding 6 feet in height, and rendered very effective in autumn by reason of the pale scarlet fruit, which, when fully ripe, and having split open, reveals the orange-coloured arils of the seeds. It, too, delights to grow in the shade.

E. FIMBRIATUS, Japan and India, and its handsome variegated form, E. fimbriatus foliis variegatus et argenteo maculatus, are rather too tender for cultivation in this country, even in southern districts, and where afforded wall protection. E. verrucosus and E. atropurpureus are also worthy of cultivation.

E. LATIFOLIUS.—Broad-leaved Spindle Tree. A European species (1730), deciduous, and growing from 10 feet to sometimes fully 20 feet in height. The leaves are bright, shining green, and much larger than those of our native species. Flowers, purplish-white, appearing in June; the capsules large, deep red, and when open contrasting very effectively with the bright orange arils in which the seeds are enveloped. It is a very distinct and beautiful, small-growing lawn tree, and succeeding, as it does, best in shade is an extra qualification.

FABIANA.

FABIANA IMBRICATA.—Chili, 1838. This is, unfortunately, not hardy in any but the milder maritime parts of England and Ireland. It is a charming shrub of Heather-like appearance, with small, crowded leaves, and pure white flowers produced in May. Planted at the base of a southern wall it does best, and where it thrives it is certainly one of our handsomest half-hardy shrubs.

FATSIA.

FATSIA JAPONICA (syns Aralia japonica and A. Sieboldii).—Japan, 1858. This is of no particular value as a flowering shrub, but being hardy in most districts, and having large handsome leaves that impart to it a tropical appearance, it is well worthy of culture. The flowers are ivory-white, and produced in large umbels towards the end of autumn, but our early frosts too often mar their beauty. In this country it grows about 10 feet high, and is usually what is termed "leggy" in appearance, and thrives well in any good loamy soil if fairly dry.

FENDLERA.

FENDLERA RUPICOLA.—Mexico, 1888. A low-growing shrub, peculiar to the dry rocky parts of the United States, particularly the south-western district. It grows about a yard high, and bears a great profusion of bluish-white flowers, that are rendered very conspicuous by reason of the bright yellow stamens. It is the only known species, and is nearly allied to the Saxifrages. Any fairly good garden soil will suit it well, but it wants to be planted where superfluous moisture is quickly carried off.

FORSYTHIA.

FORSYTHIA SUSPENSA (syn F. Fortunei and F. Sieboldii).—Japan and China, 1864. A slender-growing shrub, with variable leaves, and long, trailing shoots. The flowers are abundantly produced, are of a beautiful golden tint, and bell-shaped, and being of good substance last for a long time. Either as a wall plant, or for using in some sheltered corner, and where the branches can spread about at will, it forms a very distinct and handsome shrub, and one that is perfectly hardy and quite indifferent as regards the quality of soil in which it is planted. There are several forms of this pretty shrub, but as they do not differ to any great extent from the species, are hardly worthy of consideration.

F. suspensa intermedia is a garden hybrid, 1891.

F. VIRIDISSIMA.—Japan, 1845. This is another desirable species, but it is not comparable in point of beauty with the former. It is usually of strong erect growth, with stout shoots, wreathed with bright yellow flowers towards the end of winter. It is a very beautiful shrub, and a valuable addition to the winter or early spring flowering section.

FOTHERGILLA.

FOTHERGILLA ALNIFOLIA.—North Eastern America, 1765. This is an ungainly habited shrub, of dwarf growth, the branches being somewhat slender and crooked. The flowers are white, sweetly scented, and produced in dense terminal spikes. It is perfectly hardy.

FRAXINUS.

FRAXINUS ORNUS (syn F. argentea, F. rotundifolia, and Ornus europea).—Manna Ash. South Europe, 1730. This is a handsome tree, especially when young and vigorous, and by far the most ornamental species in cultivation. For planting in situations where large-growing subjects would be out of place this is a valuable tree, while the wealth of flowers renders it particularly interesting and effective. It rarely exceeds 30 feet in height, with leaves not unlike those of the common Ash, and conspicuous panicles of light, feathery, white petaliferous flowers, produced usually in great abundance all over the tree. Perfectly hardy.

F. Ornus serotina alba and F. Ornus serotina violacea are beautiful seedling forms that were raised in France, and on account of their dwarf habit and profusion of flowers are well worthy of attention. The flowers of the first-named variety are pure white, the stamens having at first yellow anthers, which speedily turn to a rich blackish-brown. The other differs but little, only in the flowers, which are of a distinct greyish-violet hue, while the leaves are of a darker shade of green, and the leaflets longer and narrower.

F. MARIESII.—Northern China, 1880. This is hardy in most parts of the country. The whole tree is quite glabrous except the petioles, which are clothed with a dense pubescence. Flowers pure white, and arranged in large dense panicles.

FREMONTIA.

FREMONTIA CALIFORNICA.—California, 1851. A handsome and deciduous Californian shrub, but scarcely hardy enough for the open air without protection. In Southern England and Ireland, however, it does well, and all the better if planted within the influence of the sea. The large yellow flowers are often about 2 inches across, and produced singly along the branches, while the leaves are large, lobed, and of an enticing shade of green. Planted against a wall, in good dampish loam, it succeeds well.

FUCHSIA.

FUCHSIA MACROSTEMA GLOBOSA (syn F. globosa).—Chili. This is readily recognised by the globose form assumed by the incurved sepals, while the flowers are smaller and less showy than those of F. Riccartoni. Hardihood about similar to the following.

F. RICCARTONI.—This seedling from F. m. globosa is one of the two hardiest varieties, but even this plant, except in warm, maritime districts, is by no means satisfactory. Where it does well it is a shrub of great beauty, and blooms profusely. This species has red, straight sepals, and a purple corolla. In favoured districts it may frequently be seen as much as 12 feet high, and is then during the flowering period an object of great beauty. It originated at Riccarton, near Edinburgh, about 1830.

GARRYA.

GARRYA ELLIPTICA.—California, 1818. This is a handsome shrub, with dark green coreaceous leaves, resembling very nearly those of the Evergreen Oak. The long, tassellated catkins, of a peculiar yellowish-green colour, render the plant one of much interest and beauty. As a wall plant it thrives well, the slight protection thus afforded favouring the growth and expansion of the catkins. For planting in the shrubbery it is also well suited, and where it oft-times attains to a height of 6 feet, and is bushy in proportion. It is well to bear in mind that there are male and female plants of the Garrya, and that the former is the more ornamental. Good rich, well-drained loam will suit this shrub well.

GAULTHERIA.

GAULTHERIA NUMMULARIOIDES (syn G. nummulariae and G. repens). —Himalayas. This is a neat Alpine species, with small and very dark green leaves. It likes a shady situation and vegetable soil. For planting on the rockwork, amongst tree roots, or beneath the shade of trees, the Gaultherias are particularly suitable. Light, but rich vegetable soil suits them best.

G. PROCUMBENS.—Canada Tea, or Creeping Winter-green. North America, 1762. This is of much smaller growth than the following, rarely rising to a greater height than about half a foot, with lanceolate, serrated leaves, and pendulous axillary clusters of white flowers.

G. SHALLON.—North-west America, 1826. Growing in favourable situations to fully a yard in height, this distinct evergreen shrub, which is fairly common in cultivation, is particularly valuable, as it thrives well under the shade and drip of trees. It is a rambling plant, with ovate-cordate, almost sessile leaves, and bears tiny white flowers that are succeeded by purplish fruit. G. Shallon acutifolia has more sharply pointed leaves than those of the species.

GENISTA.

GENISTA AETNENSIS (syn Spartium aetnensis).—Etna Broom. Sicily and Sardinia, 1816. This is a large-growing species of elegant growth, and remarkable for the abundance of yellow flowers with which it is literally covered in August. Than this South-European Pea-flower, perhaps not another member of the family is more worthy of culture, the neat, elegant habit of growth and profusion of flowers rendering it a plant of particular interest and beauty. It is quite hardy, thrives in any light soil if well drained, and is readily propagated from seed, which it ripens in abundance.

G. ANXANTICA.—Naples, 1818. This is a nearly allied species to our native G. tinctoria, and is of dwarf growth with a rich abundance of golden yellow flowers that are produced towards the end of summer.

G. CINEREA (syn G. ramosissima), from South Europe, is a very beautiful and desirable species, a yard high, and bearing in July slender twigs of the brightest yellow flowers.

G. EPHEDROIDES.—Corsica and Sardinia, 1832. With small and abundantly-produced flowers, this resembles Ephedra, hence its name.

G. GERMANICA.—Germany, 1773. This is a handsome rock garden shrub, of fully 18 inches in height, with arching stems and a plentiful supply of bright flowers during the summer and autumn months.

G. HISPANICA.—South-western Europe, 1759. This species resembles our common Broom, but the branches are not angular. The large, yellow, fragrant flowers appear in July. There is a charming double-flowered variety named G. hispanica flore-pleno.

G. LUSITANICA.—Portugal, 1771. This is remarkable for its opposite branches, is of spiny growth, and one of the earliest to appear in flower.

G. MONOSPERMA.—South Europe, 1690. This has white flowers, and is of value as a seaside shrub, and grows well in almost pure sand. A native of the Mediterranean coast.

G. PILOSA.—Greenweed. Europe (Britain). This is a dense prostrate native species, with bright yellow blossoms produced freely during May and June. A delightful rock shrub, and one that will succeed well almost in pure gravel.

G. PROSTRATA.—Burgundy and Alps of Jura, 1775. A small-growing species suitable for rock gardening, and of spreading bushy growth. Flowers small, but ornamental, and produced in May and June.

G. RADIATA (syn Spartium radiatum).—South Europe, 1758. This is a slender-growing shrub, about 18 inches high, with narrow leaflets, and terminal heads of yellow flowers produced in summer.

G. SAGITTALIS.—South Europe, 1750. With its peculiarly winged and jointed stems, which are of a deep green colour, this is one of the most distinct forms. The flowers are few but pretty, and with the dwarf habit render the plant an excellent subject for rockwork.

G. TINCTORIA.—Dyers' Greenweed. Europe (Britain), North and West Asia. This is a spineless species, and bears a profusion of yellow flowers from July onwards. The double-flowering variety, G. tinctoria flore-pleno, is, in so far as ornamental qualities are concerned, superior to the parent form.

G. TINCTORIA ELATIOR (syn G. elatior) grows to 12 feet in height, is of free, spreading growth, and a very handsome plant. The flowers, which are individually small and yellow, are so thickly produced that the shrub, in late summer, has the appearance of a sheet of gold.

G. TRIANGULARIS (syn G. triquetra).—South Europe, 1815. This is a decidedly good garden plant, and of neat, trailing habit. The stems are three sided, and the flowers golden yellow and plentifully produced. A native of South Europe, and perfectly hardy in almost any position.

The above include most of the hardy Genistas, though G. capitata and G. daurica, both very ornamental kinds, might be added to the list. They are all very hardy, free-flowering shrubs, of simple culture, and succeeding well in any light and rather dry soil.

GLEDITSCHIA.

GLEDITSCHIA TRIACANTHOS.—Honey Locust. United States, 1700. As an ornamental hardy tree this is well worthy the attention of planters, the pinnate and bipinnate foliage being particularly elegant, while the flowers, though individually small, are borne in such quantities of fascicled racemes as to attract notice. The stem and branches are armed with formidable prickles, but there is a form in which the prickles are absent. A native of North America, and readily cultivated in any soil of even fair quality. For town planting it is a valuable tree. There is a good weeping variety named G. triacanthos pendula.

G. SINENSIS (syn G. horrida).—China, 1774. This nearly resembles the latter, and is occasionally to be met with in cultivation in this country.

GORDONIA.

GORDONIA LASIANTHUS.—Loblolly Bay. North America, 1739. A shrub of great beauty, but one that, unfortunately, is rarely to be seen outside the walls of a botanic garden. It is of Camellia-like growth, with large, sweetly fragrant flowers and a good habit of growth.

G. PUBESCENS.—North America, 1774. This is of smaller growth than the latter, rarely exceeding about 6 feet high, with large white flowers that are rendered all the more conspicuous by the tuft of golden stamens. Both species are somewhat tender, although hailing from the coast, swampy grounds of the southern States of North America. Planted in favoured sites, they usually grow freely in light, peaty soil, or that containing a large admixture of decayed leaf soil.

GRABOWSKIA.

GRABOWSKIA BOERHAAVIAEFOLIA.—Peru, 1780. This is occasionally to be seen in sheltered and favoured gardens, but it is not to be relied upon in other than southern and seaside districts. The plant is of no particular interest to the cultivator, the outline being ungainly, while the pale blue flowers are both dull and uninteresting. It belongs to the Solanum family, and is only worth cultivating as a curiosity. Light, warm soil and a sunny position are necessities in the cultivation of this shrub.

GRISELINIA.

GRISELINIA LITTORALIS.—New Zealand, 1872. This forms a compact bush of moderate size, and is fairly hardy. The leaves are of a light, pleasing green shade, coriaceous, and glossy, and remain on the plant during winter. It is an excellent shrub for the seaside, and, moreover, will succeed well in stiff soils where many other plants would refuse to grow.

GYMNOCLADUS.

GYMNOCLADUS CANADENSIS.—Kentucky Coffee Tree. Canada, 1748. When in full leafage this is a distinct and beautiful tree, the foliage hanging in well-rounded masses, and presenting a pretty effect by reason of the loose and tufted appearance of the masses of finely-divided leaves. Leaves often 3 feet long, bipinnate, and composed of numerous bluish-green leaflets. Flowers white, borne in loose spikes in the beginning of summer, and succeeded by flat, somewhat curved brown pods. It prefers a rich, strong soil or alluvial deposit.

G. CHINENSIS.—Soap Tree. China, 1889. Readily distinguished from the American species by its much smaller and more numerous leaflets, and thicker fruit pod. It is not very hardy in this country unless in the milder sea-side districts. The leaves are used by the Chinese women to wash their hair, hence the popular name of Soap Tree.

HALESIA.

HALESIA DIPTERA (syn H. reticulata).—North America, 1758. This is not so suitable for our climate as H. tetraptera, though in southern parts of the country it forms a neat, healthy bush, and flowers freely. It is distinguished, as the name indicates, by having two wings to the seed vessel, H. tetraptera having four.

H. HISPIDA (syn Pterostyrax hispidum).—Japan, 1875. This is a shrub of perfect hardihood, free growth, and very floriferous. The flowers, which are pure white, and in long racemes, resemble much those of the Snowdrop Tree. Leaves broad and slightly dentated. It is a handsome shrub, of free growth, in light, sandy loam, and quite hardy even when fully exposed.

H. PARVIFLORA has smaller flowers than those of our commonly-cultivated plant.

H. TETRAPTERA.—Snowdrop Tree. North America, 1756. This is a very ornamental tall-growing shrub, of somewhat loose growth, and bearing flowers which resemble, both in size and appearance, those of our common Snowdrop. It is one of the most ornamental of all the small-growing American trees, and richly deserves a place in every collection, on account of the profusion with which the flowers are produced in April and May. They are snow-white, drooping, and produced in lateral fascicles of eight or ten together. It is a native of river banks in North Carolina, and is well suited for cultivation in this country. Light, peaty soil will grow it to perfection.

HALIMODENDRON.

HALIMODENDRON ARGENTEUM (syn Robinia Halimodendron).—Salt tree. A native of Asiatic Russia (1779), having silvery foliage, and pink or purplish-pink flowers, axillary or fascicled. It is a neat and pretty shrub, that is rendered valuable as succeeding well in maritime districts. Quite hardy and of free growth in sandy soil.

HAMAMELIS.

HAMAMELIS JAPONICA.—The Japanese Witch Hazel. Japan, 1862. This is a small species with lemon-yellow flowers. H. japonica arborea is a taller growing variety, with primrose-yellow petals, and a deep claret calyx. The flowers are borne in clusters in early spring. Rarely in this country do we find this species of greater height than about 8 feet, but it is of bushy growth, though somewhat straggling in appearance. As early as the beginning of January this Witch Hazel may be found in bloom, the bare branches being studded here and there with the curious-shaped flowers, these having bright yellow, twisted petals and reddish calyces. H.j. Zuccarinianais a very desirable free-flowering variety, with pale yellow petals and a greenish-brown calyx.

H. VIRGINICA.—Virginian Witch Hazel. North America, 1736. This has smaller flowers than H.j. arborea, and they are plentifully produced in autumn or early winter. In this country it assumes the shape of an open bush of about 6 feet in height, but is usually of untidy appearance from the branches being irregularly disposed.

They all delight in cool, rather moist soil, and are of value for their early-flowering nature.

HEDYSARUM.

HEDYSARUM MULTIJUGUM.—South Mongolia. Hardly ten years have elapsed since this pretty shrub was introduced into England, so that at present it is rather rare in our gardens. It is a decided acquisition, if only for the production of flowers at a time when these are scarce. Usually the flowering time is in August, but frequently in the first weeks of October the pretty flowers are still full of beauty. It is of bushy habit, from 4 feet to 5 feet high, with oblong leaflets, in number from twenty to thirty-five, which are Pea-green above and downy on the under sides. Flowers bright red, and produced in axillary racemes. It is perfectly hardy, and grows freely in porous decomposed leaf-soil.

HELIANTHEMUM.

HELIANTHEMUM HALIMIFOLIUM.—Spain, 1656. This species is of erect habit, 3 feet or 4 feet high, and with leaves reminding one of those of the Sea Purslane. It is an evergreen, and has large bright yellow flowers, slightly spotted at the base of the petals.

H. LAEVIPES (syn Cistus laevipes).—South-western Europe. A dwarf shrub, with Heath-like leaves, and yellow flowers that are produced in great abundance.

H. LASIANTHUM (syns H. formosum and Cistus formosus).—Spain and Portugal, 1780. This is a beautiful species, but not hardy unless in the South and West. It has large, bright yellow flowers, with a deep reddish-purple blotch at the base of each petal.

H. LAVENDULAEFOLIUM has lavender-like leaves, with the under surface hoary, and yellow flowers. A native of the Mediterranean regions.

H. LIBONATES.—This species bears dark green Rosemary-like leaves, and yellow flowers that are produced very abundantly. South Europe.

H. PILOSUM.—South of France, 1831. This bears white flowers that are of good substance, and about an inch across.

H. POLIFOLIUM (syn H. pulverulentum).—Europe (Britain), and North Africa. This is a neat-growing shrub, of very dwarf growth, with hairy leaves and yellow flowers; and H. polifolium roseum, has pretty rosy-red flowers.

H. UMBELLATUM.—South Europe, 1731. A neat, small-growing species, with white flowers and glossy-green leaves covered with a rusty-white tomentum beneath.

H. VULGARE.—Common Rock Rose. Europe (Britain), North Africa, and West Asia. A widely distributed native plant, of dwarf growth, with linear-oblong, hairy leaves, and usually yellow flowers. H. vulgare nummularium differs in having the leaves green and sub-orbicular, with yellow flowers. H. vulgare barbaturn is of erect habit, with silky, hairy, oval leaves. H. vulgare mutabile bears pale rose flowers, marked with yellow at the base. H. vulgare grandiflorum is remarkable for the large, bright yellow flowers, and is one of the most beautiful and worthy varieties. H. vulgare ovalifolium (syn H. serpyllifolium) bears yellow flowers and ovate leaves, with the margins revolute. H. vulgare hyssopifolium bears reddish flowers, but the colouring varies considerably, and saffron is not uncommon.

The Rockroses are very valuable plants, in that they will succeed on poor, gravelly banks where few other plants could eke out an existence. They cannot withstand stiff soil, nor that at all inclined to be damp, their favourite resorts being exposed, rocky ground, and dry, gravelly banks. Being readily increased from cuttings, which take root well under a hand glass or in a cool house, it is advisable, at least with the more tender forms, to have at hand a stock, so that blanks in the shrubbery may be filled up.

HIBISCUS.

HIBISCUS SYRIACUS (syn Althaea frutex).—Syrian Mallow. Syria, 1596. An old occupant of our gardens, and one that cannot be too freely cultivated. When favourably situated, it often reaches 6 feet in height, with three-lobed, neatly-toothed leaves, and with large, showy blossoms that are borne towards the end of summer. The typical species has purplish flowers, with a crimson spot at the base of each petal, but others, varying in colour from snow-white to purple and blue, are common in cultivation. H. syriacus coelestis bears bright blue flowers, while H. syriacus variegatus has beautifully variegated foliage. Of the double-flowered forms, there are several beautiful and worthy plants, the following list containing some of the best varieties of this popular shrub:—

H. syriacus albo-pleno. " amaranthus. " amplissima. " ardens. " caerulea plena. " carnea plena. " De la Veuve. " elegantissimum. " fastuosa. " Lady Stanley. " Leopoldii. " lilacina plena. " paeoniaeflora. " puniceus plenus. " rosea plena. " rubra plena. " spectabilis plena. " violacea.

HIPPOPHAE.

HIPPOPHAE RHAMNOIDES.—Sea Buckthorn, or Sallow Thorn. Though generally considered as a sea-side shrub, the Sea Buckthorn is by no means exclusively so, thriving well, and attaining to large dimensions, in many inland situations. The flowers are not at all conspicuous, but this is amply compensated for by the beautiful silvery-like leaves and wealth of fruit borne by the shrub. In not a few instances, for fully a foot in length, the branches are smothered with crowded clusters of bright orange berries, and which render the shrub during November and December both distinct and effective. It does best in sandy soil, and is readily increased from suckers, which are usually plentifully produced by old plants. For sea-side planting it is one of our most valuable shrubs, succeeding, as it does, well down even to high water mark, and where the foliage is lashed with the salt spray.

HOLBOELLIA.

HOLBOELLIA LATIFOLIA (syn Stauntonia latifolia).—Himalayas, 1840. An evergreen climbing shrub that is more often found under glass than out of doors. In the South of England, however, it is quite hardy against a sunny wall. It grows 12 feet high, with shining green leathery leaves, and fragrant purplish-green flowers. H. latifolia angustifolia has decidedly narrower leaves than the species, but is in no other way different.

HYDRANGEA.

HYDRANGEA ARBORESCENS.—North America, 1736. This is a plant of large growth, but the flowers are greenish-white, and by no means conspicuous.

H. HORTENSIS (syn Hortensia opuloides).—China, 1790. This is an old-fashioned garden shrub that is only hardy in the south and west of these islands and in the vicinity of the sea. In some of the forms nearly all the flowers are sterile, the calyx-lobes being greatly expanded, and in others the outer flowers only are sterile. According to the nature of the soil the flowers vary much in colour, some being pure white, others pink, and others of varying shades of blue. There are some very beautiful and distinct varieties, such as H. hortensis japonica; H. hortensis Otaksa, with large panicles of sterile blue flowers; H. hortensis rosea-alba, with large rosy flowers; H. hortensis Thomas Hogg, a very free-flowering and welcome form; H. hortensis mandschurica, and H. hortensis stellata flore-pleno, with partially double flowers, are worthy of attention.

H. PANICULATA.—Japan, 1874. This is one of the most distinct species, in which the flower-heads are elongated, not flat, as in most other species, and from which the finest form in cultivation has been obtained. This is H. paniculata grandiflora, in which the flowers are sterile and pure white, forming large panicles often a foot in length. It is a magnificent variety, and, being perfectly hardy, should be extensively planted for ornament. The flowers are produced in late summer, but remain in good form for fully two months, dying off a rich reddish hue.

H. QUERCIFOLIA.—Oak-leaved Hydrangea. Florida, 1803. This species has neatly lobed leaves, and terminal panicles of pinky-white, but partially barren, flowers.

H. SCANDENS.—Climbing Hydrangea. Japan, 1879. This is not very hardy, but with the protection of a sunny wall it grows freely.

The Hydrangeas require a rich, loamy soil, and, unless in maritime districts, a warm and sheltered situation. They are readily propagated by means of cuttings.

HYMENANTHERA.

HYMENANTHERA CRASSIFOLIA.—A curious New Zealand shrub with rigid ashy-coloured branches, and small leathery leaves. The flowers are violet-like in colour, but by no means conspicuous. The small white berries which succeed the flowers are, in autumn, particularly attractive, and very ornamental. It is perfectly hardy and of free growth in light peaty earth.

HYPERICUM.

HYPERICUM ANDROSAEMUM.—Tutsan, or Sweet Amber. Europe (Britain). A pretty native species, growing about 2 feet high, with ovate leaves having glandular dots and terminal clustered cymes of yellow flowers.

H. AUREUM.—South Carolina and Georgia, 1882. This soon forms a neat and handsome plant. The flowers are unusually large, and remarkable for the tufts of golden-yellow stamens with which they are furnished.

H. CALYCINUM.—Aaron's Beard, or Rose of Sharon. South-east Europe. This is a well-known native species of shrubby growth, bearing large yellow flowers from 3 inches to 4 inches in diameter. It is a prostrate plant, with coriaceous glossy leaves with small pellucid dots, and of great value for planting in the shade.

H. ELATUM is a spreading species from North America (1762), growing to fully 4 feet in height, and bearing terminal corymbs of large, bright yellow flowers in July and August. Leaves rather large, oblong-ovate, and revolute. On account of its spreading rapidly from the root, this species requires to be planted where it will have plenty of room.

H. HIRCINUM.—Goat-scented St. John's Wort. Mediterranean region, 1640. A small-growing and slender species, with oblong-lanceolate leaves 2 inches long, and producing small yellow flowers in terminal heads. There is a smaller growing form known as H. hircinum minus. The plant emits a peculiar goat-like odour.

H. MOSERIANUM is a beautiful hybrid form with red anthers.

H. OBLONGIFOLIUM (syns H. Hookerianum and H. nepalensis).—Nepaul, 1823. An evergreen species, about 4 feet high, with oblong, pellucid, dotted leaves, and deep golden, somewhat waxy flowers at the end of summer.

H. PROLIFICUM.—North America, 1758. This is a much branched twiggy shrub, about 4 feet high, with small, linear-lanceolate leaves, thickly studded with pellucid dots. Flowers not very large, five-petalled, and of a pleasing bright yellow colour. The allied if not identical H. Kalmiana is worthy of being included in a selection of these plants.

H. URALUM.—Nepaul, 1823. A neat but fragile species that attains to about a yard in height. Leaves rather small, elliptic, almost stalkless, and perforated with transparent dots. Flowers small and of a bright golden yellow.

H. fasciculatum, H. pyrimidatum, and H. patulum are all worthy of attention, where a good representative collection is of importance. The Hypericums succeed best when planted in a rather sandy and not too dry loam, and they are readily increased either from divisions or by means of cuttings.

IDESIA.

IDESIA POLYCARPA (syns Flacourtica japonica and Polycarpa Maximowiczii).—A Japanese tree of small growth, and only introduced to this country in 1866. It is a handsome, hardy species, bearing large, bright-green leaves with conspicuous crimson footstalks, often 4 inches across, and of a glaucous tint on the under sides. The deliciously fragrant flowers are greenish-white or yellowish-green, and produced in graceful drooping racemes. In southern England it does well, and, being a tree of unusual beauty of both leaves and flowers, is well worthy of attention. Rich loam, not too stiff, will grow the Idesia well.

ILEX.

ILEX AQUIFOLIUM.—Common Holly. Europe (Britain) and West Asia. Though the Hollies are not usually reckoned ornamental for the sake of their flowers, their berries are highly so. Some of them are nevertheless deliciously fragrant when in bloom. The leaves of this, our native species, in their typical form are oblong-ovate, wavy, and deeply spiny-toothed. The tree flowers in May and June, while the clusters of bright red berries ripen in autumn, persist all the winter, and sometimes even hang on tree till a second crop is matured, provided they are not devoured by birds during severe weather. The varieties are very numerous, and differ chiefly in the form and toothing of the leaves, which are variegated in many cases, their size and form, and in the colour of the berries in a few instances.

I. Aquifolium albo-marginata has ovate, nearly flat, spiny-serrate leaves, with a narrow silvery margin, and fruits freely. I. Aquifolium fructu albo has white berries; in I. Aquifolium fructu luteo they are yellow and very abundantly produced; and in I. Aquifolium fructu nigro they are black. I. Aquifolium handsworthensis has elliptic-oblong spiny leaves, with a creamy-white margin and marbled with gray. Grafted trees bear berries in great profusion from the time they are only a foot high, and are highly ornamental. I. Aquifolium Hodginsii has large, broadly oblong-ovate, slightly spiny leaves, and large crimson-red berries that ripen late in autumn. I. Aquifolium Hodginsii aurea is a sub-variety with a broad golden margin to the leaves, and the disc splashed with gray. Beautiful and distinct is I. Aquifolium Lawsoniana, with ovate, flat, almost spineless leaves, heavily and irregularly blotched with yellow in the centre. The berries are of a brilliant red. The variety differs from Milkmaid in having flat, nearly entire leaves. I. Aquifolium pendula has a wide, rounded, drooping head, but otherwise does not differ from the type. Many others bear berries, but the above are all very distinct forms.

I. OPACA.—American Holly. United States, 1744. The leaves of this species are oblong or oval, small, spiny-serrate, and of a dark opaque green. The berries, which ripen in autumn, are small, bright red, and very liable to be eaten by birds. In America this Holly is put to precisely the same purposes as the common Holly is in Europe. It is perfectly hardy here.

ILLICIUM.

ILLICIUM FLORIDANUM, from Florida (1771), is a beautiful but uncommon shrub, probably on account of its being tender and susceptible to injury by frost, unless in the warmer and more favoured parts of the country. The fragrant flowers are of a purplish-rose, while the foliage is neat and of a pleasing green.

I. ANISATUM (syn I. religiosum), from China and Japan (1842), is too tender for outdoor culture in this country.

INDIGOFERA.

INIDGOFERA GERARDIANA (syns I. floribunda and I. Dosua).—India, 1842. This forms a compact dwarf bush in the open, but is still better suited for covering a wall, the growth and floriferousness being then much increased. The foliage is neat and Pea-green, while the bright pink Pea-like flowers are produced in long racemes. It is a pretty bush, and grows freely enough in any good garden soil, but very fine flowering specimens may be seen in light, sandy soil of a peaty nature. There is a white flowered variety named I. Gerardiana alba.

ITEA.

ITEA VIRGINICA.—North America, 1744. This is a neat, deciduous shrub of 3 feet or 4 feet in height. The ovate-lanceolate leaves are of a light greyish-green, and the small white flowers are produced in dense racemes or spikes. Planted in a somewhat shady place, and in rather cool, damp soil, this little shrub does well and flowers profusely.

JAMESIA.

JAMESIA AMERICANA.—Rocky Mountains and Colorado, 1865. Amongst early spring-flowering shrubs this pretty but neglected plant is one of the best, of perfect hardihood, for it stands the vigour of our winters with impunity, and of dense thick growth; it is suitable for using in a variety of ways, as well as for purely ornamental purposes. The leaves are oval and neatly dentated, and the flowers individually of large size, pure white, and produced in terminal bunches. Cool soil and a shady situation would seem to suit the plant admirably, but for screen purposes in the rock garden or border it is invaluable on account of the strong and dense twigs.

JASMINUM.

JASMINUM FRUTICANS.—South Europe, 1570. An evergreen species, well adapted, from its rather stiff and upright growth, for planting alone. It has trifoliolate leaves and showy yellow flowers.

J. HUMILE.—India, 1656. A hardy species of dwarf growth, and bearing beautiful golden flowers produced in summer.

J. NUDIFLORUM.—Naked Jasmine. China, 1844. A showy and well-known species, from China, with numerous, usually solitary yellow flowers, ternate leaves, and flexible branches. The variety J. nudiflorum aureo-variegatum has golden-variegated leaves.

J. OFFICINALE.—Northern India to Persia, 1548. The white-flowered Jasmine of our gardens is a very beautiful and desirable clambering shrub, either for wall covering, for planting by tree stumps, rooteries, or rockeries, or for screening and draping the pergola or garden latticework. From its great hardihood, vigour of growth, and beauty of flowers, it is certainly one of the most deservedly popular of wall shrubs. The branches are deep green, angular, and flexible, the leaves pinnate, and the flowers pure-white and sweetly-scented. The variety J. officinale affine has flowers that are individually larger than those of the species; J. officinale aurea has badly variegated leaves; J. officinale grandiflorum and J. officinale grandiflorum majus, are also desirable kinds.

J. PUBIGERUM GLABRUM (syn J. Wallichianum), from North-west India, is not well-known, being tender in most parts of the country.

J. REVOLUTUM.—India, 1812. This has persistent dark, glossy-green leaves, and fragrant, bright yellow flowers, produced in large, terminal clusters. From India, but perfectly hardy as a wall plant, and for which purpose, with its bright evergreen leaves, it is well suited.

As regards soil, the Jasmines are very accommodating, and are propagated by layers or cuttings.

KADSURA.

KADSURA JAPONICA.—Japan, 1846. This is a small-growing shrub, with lanceolate and pointed leaves, that are remotely dentated. The flowers are not very showy, being of a yellowish-white colour and about an inch across. They are produced both terminal and axillary, and in fair abundance. The scarlet fruits are arranged in clusters, and when fully ripe are both showy and interesting. Generally speaking this shrub suffers from severe frost, but as only the branch tips are injured, it shoots freely from the stock. It produces its flowers in the autumn. There is a variety with variegated leaves.

KALMIA.

KALMIA ANGUSTIFOLIA.—Sheep Laurel. Canada, 1736. This is at once distinguished from K. latifolia by its much smaller and narrower leaves and smaller flowers, which latter are, however, of brighter tint and more plentifully produced. It rarely exceeds 2 feet in height. Of this there are two very distinct forms, that named K. angustifolia pumila, being of neat and dense small growth; and K. angustifolia rubra, in which the flowers are of an unusually deep red.

K. GLAUCA.—Canada and Sitcha, 1767. This, which has lilac-purple flowers, produced in early spring, is not a very desirable species, being rather straggling of growth and with few flowers.

K. HIRSUTA.—Hairy-leaved Kalmia. South-east Virginia to Florida, 1786. This is at once distinguished by the rather rough and hairy foliage and few rosy-tinted flowers. It is of dwarf, neat growth.

K. LATIFOLIA.—Calico Bush, or Mountain Laurel. Alleghanies, Canada, and Western Florida, 1734. A favourite shrub in every garden where the conditions of soil will allow of its being successfully cultivated. In peaty soil, or light, friable loam and leaf soil, it forms a dense, round-headed bush, often 8 feet in height, and nearly as much through, with pleasing green leaves, and dense clusters of beautiful pink, wax-like flowers. The flowering period commences in May, and usually extends to the end of July. This is a choice shrub of great hardihood, and one of the handsomest flowering in cultivation. There is a still more beautiful form named K. latifolia major splendens, and one with small Myrtle-like foliage named K. latifolia myrtifolia.

The members of this handsome family are, as a rule, partial to cool, damp soil, peat of a light, sandy nature being preferred. They thrive well where Azaleas and Rhododendrons will succeed. In bold masses they have a fine effect, but a well developed standard specimen of the commonly cultivated species is highly ornamental.

KERRIA.

KERRIA JAPONICA (syn Corchorus japonicus).—Japan, 1700. A Japanese shrub, the double-flowered variety of which, K. japonica flore-pleno, is one of our commonest wall plants. The orange-yellow flowers, produced in great rosettes, are highly ornamental, and have earned for the shrub a well-known name. It succeeds well almost anywhere, and, though usually seen as a wall plant, is perfectly hardy, and forms a neat shrub for the open border. There is a form in which the leaves are variegated, and known under the name of K. japonica variegata.

KOELREUTERIA.

KOELREUTERIA PANICULATA.—Northern China, 1763. Whether for its foliage or flowers, this small-growing tree is worthy of a place. Though of rather irregular growth, the beautiful foliage and large panicles of yellowish flowers, which stand well above the leaves, make the shrub (for it does not in this country attain to tree height), one of particular interest, and a valuable aid in ornamental planting. In a sheltered corner, and planted in rich soil, it grows and flowers freely.

LABURNUM.

LABURNUM ADAMI (syn Cytisus Adami).—A graft hybrid form between the common Laburnum and Cytisus purpureus, the result being flowers of the Laburnum, the true Cytisus purpureus, and the graft hybrid between the two. It was raised by Jean Louis Adam in 1825. It is a curious and distinct tree, worthy of culture if only for the production of three distinct kinds of flowers on the same plant.

L. ALPINUM (syn Cytisus alpinus).—Scotch Laburnum. Europe, 1596. This very closely resembles the common Laburnum, but it is of larger growth, and flowers later in the season. The flowers, too, though in longer racemes, are usually less plentifully produced. It grows 30 feet high. There is a weeping form, L. alpinum pendulum, and another with fragrant flowers, named L. alpinum fragrans, as also a third, with very long racemes of flowers, named L. alpinum Alschingeri.

L. CARAMANICUM.—Asia Minor, 1879. A bushy shrub of vigorous habit, with trifoliolate and petiolate leaves of a pale green colour, thick and tough, and brightly polished on the upper surface. Flowers bright yellow, the calyx being helmet-shaped and rusty-red. It is a beautiful but uncommon shrub, and succeeds very well in chalky or calcareous soil. Flowers in July.

L. VULGARE (syn Cytisus Laburnum).—Common Laburnum. Southern France to Hungary, 1596. This is one of our commonest garden and park trees, and at the same time one of the most beautiful and floriferous. The large, pendulous racemes of bright yellow flowers are, when at their best in May, surpassed neither in quantity nor beauty by those of any other hardy tree. There are several varieties of this Laburnum—a few good, but many worthless, at least from a garden point of view. L. vulgare Parkesii is a seedling form, bearing large racemes of deep-coloured flowers, often 14 inches long; L. vulgare Watereri was raised in the Knap Hill Nursery, Surrey, and is one of the most distinct and beautiful of the many forms into which the Laburnum has been sub-divided. The flower racemes are very long and richly coloured. L. vulgare quercifolium and L. vulgare sessilifolium are fairly well described by their names; L. vulgare fragans differs only in having sweetly-scented flowers; L. vulgare involutum has curiously-curled leaves; while L. vulgare aureum, where it does well, is a beautiful and distinct form.

LARDIZABALA.

LARDIZABALA BITERNATA.—Chili, 1848. Requires wall protection, there being few situations in which it will succeed when planted in the open. It is a tall, climbing shrub, with dark green persistent leaves, and bearing purplish flowers in drooping racemes in mid-winter. Planted in rather dry soil, at the base of a sunny wall, this shrub forms a by no means unattractive covering, the twice ternate, glossy leaves being fresh and beautiful the winter through.

LAPAGERIA.

LAPAGERIA ROSEA.—Chili, 1847. This is, unfortunately, not hardy, unless in favoured maritime districts, but in such situations it has stood unharmed for many years, and attained to goodly proportions. It is a beautiful climber, with deep-green leaves, and large, fleshy, campanulate flowers of a deep rose colour. There is a white-flowered form called L. alba, introduced from Chili in 1854. Planted on an east aspect wall, and in roughly broken up peat and gritty sand, it succeeds well.

LAVANDULA.

LAVANDULA VERA (syn L. Spica).—Common Lavender. South Europe, 1568. A well-known and useful plant, but of no particular value for ornamental purposes. It is of shrubby growth, with narrow-lanceolate, hoary leaves, and terminal spikes of blue flowers.

LAVATERA.

LAVATERA ARBOREA.—Tree Mallow. Coasts of Europe, (Britain). A stout-growing shrub reaching in favourable situations a height of fully 6 feet, with broadly orbicular leaves placed on long stalks. The flowers are plentiful and showy, of a pale purplish-red colour, and collected into clusters. It is a seaside shrub succeeding best in sheltered maritime recesses, and when in full flower is one of the most ornamental of our native plants. There is also a beautiful variegated garden form, L. a. variegata.

LEDUM.

LEDUM LATIFOLIUM (syn L. groenlandicum).—Wild Rosemary, or Labrador Tea. This is a small shrub, reaching to about 3 feet in height, indigenous to swampy ground in Canada, Greenland, and over a large area of the colder parts of America. Leaves oval or oblong, and plentifully produced all over the plant. Flowers pure white, or slightly tinted with pink, produced in terminal corymbs, and usually at their best in April. A perfectly hardy, neat-growing, and abundantly-flowered shrub, but one that, somehow, has gone greatly out of favour in this country. This plant has been sub-divided into several varieties, that are, perhaps, distinct enough to render them worthy of attention. They are L. latifolium globosum, with white flowers, borne in globose heads, on the short, twiggy, and dark-foliaged branches. L. latifolium angustifolia has narrower leaves than those of the species, while L. latifolium intermedium is of neat growth and bears pretty, showy flowers.

L. PALUSTRE.—Marsh Ledum. This is a common European species, growing from 2 feet to 3 feet high, with much smaller leaves than the former, and small pinky-white flowers produced in summer. It is an interesting and pretty plant. The Ledums succeed best in cool, damp, peaty soil.

LEIOPHYLLUM.

LEIOPHYLLUM BUXIFOLIUM (syns L. thymifolia, Ammyrsine buxifolia and Ledum buxifolium).—Sand Myrtle. New Jersey and Virginia, 1736. This is a dwarf, compact shrub from New Jersey, with box-like leaves, and bunches of small white flowers in early summer. For using as a rock plant, and in sandy peat, it is an excellent subject, and should find a place in every collection.

LESPEDEZA.

LESPEDEZA BICOLOR (syn Desmodium penduliflorum).—North China and Japan. A little-known but beautiful small-growing shrub, of slender, elegant growth, and reaching, under favourable culture, a height of about 6 feet. The leaves are trifoliolate, small, and neat, and the abundant racemes of individually small, Pea-shaped flowers are of the richest and showiest reddish-purple. Being only semi-hardy will account for the scarcity of this beautiful Japanese shrub, but having stood uninjured in all but the coldest parts of these islands should induce lovers of flowering shrubs to give it a fair chance.

LEUCOTHOE.

LEUCOTHOE AXILLARIS (syn Andromeda axillaris).—North America, 1765. This is of small growth, from 2 feet to 3 feet high, with oval-pointed leaves and white flowers in short racemes produced in May and June. It is not a very satisfactory species for cultivation in this country.

L. CATESBAEI (syns Andromeda Catesbaei and A. axillaris).—North America. This has white flowers with an unpleasant odour like that of Chestnut blossoms, but is worthy of cultivation, and succeeds best in cool sandy peat or friable yellow loam.

L. DAVISIAE, from California (1853), is a very handsome evergreen shrub, of small and neat growth, and will be found an acquisition where compact shrubs are in demand. The leaves are small, of a deep green colour, and remain throughout the year. Flowers produced in great abundance at the branch tips, usually in dense clusters, and individually small and pure white.

L. RECURVA (syn Andromeda recurva).—North America. A very distinct plant on account of the branch tips being almost of a scarlet tint, and thus affording a striking contrast to the grayish-green of the older bark. The flowers are pinky-white and produced in curving racemes and abundantly over the shrub. Like other members of the family it delights to grow in cool sandy peat.

LEYCESTERIA.

LEYCESTERIA FORMOSA, from Nepaul (1824), is an erect-growing, deciduous shrub, with green, hollow stems, and large ovate, pointed leaves of a very deep green colour. The flowers are small, and white or purplish, and produced in long, pendulous, bracteate racemes from the axils of the upper leaves. It is one of the most distinct and interesting of hardy shrubs, the deep olive-green of both stem and leaves, and abundantly-produced and curiously-shaped racemes, rendering it a conspicuous object wherever planted. Perfectly hardy, and of free, almost rampant growth in any but the stiffest soils. Cuttings root freely and grow rapidly.

LIGUSTRUM.

LIGUSTRUM IBOTA (syn L. amurense).—Japan, 1861. A compact growing species, about 3 feet in height, with small spikes of pure white flowers produced freely during the summer months.

L. JAPONICUM (syns L. glabrum, L. Kellennanni, L. Sieboldii and L. syringaeflorum).—Japan Privet. This is a dwarf-growing species rarely exceeding 4 feet in height, with broad, smooth, glossy-green leaves, and large compound racemes of flowers. There are several varieties, including L. japonicum microphyllum, with smaller leaves than the parent; and one with tricoloured foliage and named L. japonicum variegatum.

L. LUCIDUM (syns L. magnoliaefolium and L. strictum).—Shining-leaved Privet, or Woa Tree. China, 1794. A pretty evergreen species, with oval leaves, and terminal, thyrsoid panicles of white flowers. It is an old inhabitant of our gardens, and forms a somewhat erect, twiggy bush, of fully 10 feet in height. Of this there are two varieties, one with larger bunches of flowers, and named L. lucidum floribundum, and another with variegated leaves, L. lucidum variegatum. L. lucidum coriaceum (Leathery-leaved Privet) is a distinct variety, with thick, leathery-green leaves, and dense habit of growth.

L. OVALIFOLIUM (syn L. californicum).—Oval-leaved Privet. Japan, 1877. This is a commonly-cultivated species, with semi-evergreen leaves, and spikes of yellowish-white flowers. It is a good hedge plant, and succeeds well as a town shrub. There are several variegated forms, of which L. ovalifolium variegatum (Japan, 1865) and L. ovalifolium aureum are the best.

L. QUIHOI.—China, 1868. This is a much valued species, as it does not flower until most of its relations have finished. Most of the Privets flower at mid-summer, but this species is often only at its best by the last week of October and beginning of November. It forms a straggling freely-branched shrub, of fully 6 feet in height and nearly as much through, with dark shining-green oblong leaves, and loose terminal panicles of pure white, powerfully-scented flowers. It flourishes, like most of the Privets, on poor soil, and is a little-known species that note should be made of during the planting season.

L. SINENSE (syns L. villosum and L. Ibota villosum).—Chinese Privet. China, 1858. This is a tall deciduous shrub, with oblong and tomentose leaves, and flowers in loose, terminal panicles and produced freely in August. L. sinense nanum is one of the prettiest forms in cultivation. It is almost evergreen, with a horizontal mode of growth, and dense spikes of crearny-white flowers, so thickly produced as almost to hide the foliage from view. It is a most distinct and desirable variety.

L. VULGARE.—Common Privet. Although one of our commonest shrubs, this Privet can hardly be passed unnoticed, for the spikes of creamy-white flowers, that are deliciously scented, are both handsome and effective. Of the common Privet there are several distinct and highly ornamental forms, such as L. vulgare variegatum, L. vulgare pendulum, having curiously-creeping branches, and the better-known and valuable L. vulgare sempervirens (syn L. italicum), the Italian Privet.

LINNAEA.

LINNAEA BOREALIS.—Twin Flower. A small and elegant, much-creeping evergreen shrub, with small, ovate crenate leaves, and pairs of very fragrant, pink flowers. Two conditions are necessary for its cultivation—a half-shaded aspect where bottom moisture is always present, and a deep, rich, friable loam. A native of Scotland and England, flowering in July.

LIPPIA.

LIPPIA CITRIODORA (syns Aloysia citriodora and Verbena triphylla).—Lemon-scented Verbena. Chili, 1794. With its slender branches and pale green, pleasantly-scented, linear leaves, this little plant is a general favourite that needs no description. The flowers are not very ornamental, being white or lilac, and produced in small, terminal panicles. A native of Chili, it is not very hardy, but grown against a sunny wall, and afforded the protection of a mat in winter, with a couple of shovelfuls of cinders heaped around the stem, it passes through the most severe weather with little or no injury, save, in some instances, the branch tips being killed back. Propagated readily from cuttings placed in a cool frame or under a hand-light.

LIRIODENDRON.

LIRIODENDRON TULIPIFERA.—Tulip Tree. North America, 1688. One of the noblest hardy exotic trees in cultivation. The large, four-lobed, truncate leaves, of a soft and pleasing green, are highly ornamental, and are alone sufficient to establish the identity of the tree. Flowers large, yellow, and sweet-scented, and usually freely produced when the tree has attained to a height of between 20 feet and 30 feet. When we consider the undoubted hardihood of the tree and indifference to soil, its noble aspect, handsome foliage that is so distinct from that of any other tree, and showy flowers, we feel justified in placing it in the very first rank of ornamental trees. L. tulipifera integrifolia has entire leaves, which render it distinct from the type; L. tulipifera fastigiata, or pyramidalis, is of erect growth; L. tulipifera aurea, with golden foliage; and L. tulipifera crispa, with the leaves curiously undulated—a peculiarity which seems constant, but is more curious than beautiful. Few soils come amiss to the Tulip Tree, it thriving well in that of very opposite descriptions—loam, almost pure gravel, and alluvial deposit.

LONICERA.

LONICERA CAPRIFOLIUM.—Europe. This species resembles L. Periclymenum, but is readily distinguished by the sessile flower-heads, and fawny-orange flowers.

L. FLEXUOSA (syn L. brachypoda).—Japan, 1806. This is a pretty species, and one of the most useful of the climbing section. By its slender, twining, purplish stems, it may at once be distinguished, as also by the deep green, purplish-tinted leaves, and sweetly-scented flowers of various shades of yellow and purple. A native of China, and perfectly hardy as a wall plant. L. flexuosa aureo-reticulata is a worthy variety, in which the leaves are beautifully netted or variegated with yellow.

L. FRAGRANTISSIMA.—China, 1845. This species is often confounded with L. Standishii, but differs in at least one respect, that the former is strictly a climber, while the latter is of bushy growth. The leaves, too, of L. Standishii are hairy, which is not the case with the other species. It is a very desirable species, with white fragrant flowers, produced during the winter season.

L. PERICLYMENUM.—Honeysuckle, or Woodbine. An indigenous climbing shrub, with long, lithe, and twisted cable-like branches, and bearing heads of sweetly-scented, reddish-yellow flowers. This is a favourite wild plant, and in the profusion and fragrance of its flowers it is surpassed by none of the exotic species. There are several distinct nursery forms of this plant, including those known as L. Periclymenum Late Dutch, L. Periclymenum Early Cream, and L. Periclymenum odoratissimum; as also one with variegated foliage.

L. SEMPERVIRENS.—Scarlet Trumpet Honeysuckle. A North American evergreen species (1656), with scarlet, almost inodorous flowers, produced freely during the summer. For wall covering it is one of the most useful of the family. The variety L. sempervirens minor is worthy of attention.

L. STANDISHII, a Chinese species (1860), has deliciously fragrant while flowers, with a slight purplish tint, and is well worthy of attention, it soon forming a wall covering of great beauty.

L. TATARICA.—-Tartarian Honeysuckle. Tartary, 1752. This is a very variable species, in so far at least as the colour of flowers is concerned, and has given rise to several handsome varieties. The typical plant has rosy flowers, but the variety L. tatarica albiflora has pure white flowers; and another, L. tatarica rubriflora has freely produced purplish-red flowers.

L. XYLOSTEUM (syn Xylosteum dumetorum).—Fly Honeysuckle. Europe (England) to the Caucasus. The small, creamy-white flowers of this plant are not particularly showy, but the scarlet berries are more conspicuous in September and October. The gray bark of the branches has also a distinct effect in winter when grown in contrast to the red-barked species of Cornus, Viburnum, and yellow-barked Osier. It is one of the oldest occupants of British shrubberies. L. Xylosteum leucocarpum has white berries; those of L. Xylosteum melanocarpum are black; and in L. Xylosteum xanthocarpum they are yellow.

The Honeysuckles are all of the readiest culture, and succeed well in very poor soils, and in that of opposite qualities. Propagated from cuttings or by layering.

LOROPETALON.

LOROPETALON CHINENSE.—Khasia Mountains and China, 1880. This is a pretty and interesting shrub belonging to the more familiar Witch Hazel family. Flowers clustered in small heads, the calyx pale green, and the long linear petals almost pure white. Being quite hardy, and interesting as well as ornamental, should insure this Chinese shrub a place in every good collection.

LYCIUM.

LYCIUM BARBARUM.—Box Thorn, or Tea Tree. North Asia, 1696. A pretty lax, trailing shrub, with long, slender, flexible twigs, small linear-lanceolate leaves, and rather sparsely-produced lilac or violet flowers. Planted against a wall, or beside a stout-growing, open-habited shrub, where the peculiarly lithe branches can find support, this plant does best. Probably nowhere is the Box Thorn so much at home as in seaside places, it then attaining to sometimes 12 feet in height, and bearing freely its showy flowers during summer, and the bright scarlet or orange berries in winter.

L. EUROPAEUM.—European Box Thorn. South Europe, 1730. This is a spiny, rambling shrub, that may often be seen clambering over some cottage porch, or used as a fence or wall plant in many parts of England. It often grows nearly 20 feet long, and is then a plant of great beauty, with linear-spathulate leaves of the freshest green, and pretty little pink or reddish flowers. For quickly covering steep, dry banks and mounds where few other plants could exist this European Box Thorn is invaluable. Either species will grow in very poor, dry soil, and is readily propagated by means of cuttings.

LYONIA.

LYONIA PANICULATA (syns L. ligustrina, Andromeda globulifera, A. pilifera, and Menziesia globularis).—North America, 1806. This species grows about a yard high, with clustered, ovate leaves, and pretty, pinky, drooping flowers.

MACLURA.

MACLURA AURANTIACA.—Osage Orange, or Bow-wood. North America, 1818. This is a wide-spreading tree with deciduous foliage, and armed with spines along the branches. The leaves are three inches long, ovate and pointed, and of a bright shining green. Flowers rather inconspicuous, being green with a light tinge of yellow, and succeeded by fruit bearing a resemblance when ripe to the Seville orange. It is hardy, and grows freely in rather sandy or gravelly soil.

MAGNOLIA.

MAGNOLIA ACUMINATA.—Cucumber Tree. North America, 1736. This is a large and handsome species, of often as much as 50 feet in height, and with a head that is bushy in proportion. The leaves are 6 inches long, ovate and pointed, and of a refreshing shade of green. Flowers greenish-yellow, sweetly scented, and produced abundantly all over the tree. They are succeeded by small, roughish fruit, resembling an infant cucumber, but they usually fall off before becoming ripe.

M. CAMPBELII.—Sikkim, 1868. This is a magnificent Indian species, but, unfortunately, it is not hardy except in the favoured English and Irish localities. The leaves are large, and silky on the undersides, while the flowers are crimson and white, and equally as large as those of the better-known M. grandiflora.

M. CONSPICUA (syn M. Yulan).—Yulan. China, 1789. A large-growing shrub, with Pea-green, deciduous foliage, and large, pure white flowers that oft get damaged by the spring frosts. M. conspicua Soulangeana is a supposed hybrid between M. conspicua and M. obovata. Whatever may be the origin of this Magnolia, it is certainly a handsome and showy plant of very vigorous growth, producing freely its white, purple-tinted flowers, and which last for a long time in perfection. There are several other varieties, including M. conspicua Soulangeana nigra, with dark purplish flowers; M. conspicua Alexandrina, M. conspicua Soulangeana speciosa, and M. conspicua Norbertii.

M. CORDATA, a native of the Southern Alleghanies (1801), is still rare in collections. It is a small-growing, deciduous species, with yellow flowers, that are neither scented nor showy.

M. FRASERI (syn M. auriculata).—Long-leaved Cucumber Tree. North America, 1786. This species has distinctly auriculated leaves and large, yellowish-white, fragrant flowers.

M. GLAUCA.—Laurel Magnolia. North America, 1688. This is one of the commonest species in our gardens, and at the same time one of the hardiest. It is of shrub size, with Laurel-like leaves, and sweetly-scented, small, pure white flowers, produced about the end of June.

M. GRANDIFLORA.—North America, 1737. One of the handsomest species, with very large, glossy, evergreen leaves, and deliciously odoriferous, creamy-white flowers, that are often fully 6 inches across. It is usually seen as a wall plant, and the slight protection thus afforded is almost a necessity in so far as the development of the foliage and flowers is concerned. M. grandiflora exoniensis (Exmouth Magnolia) is a very handsome form.

M. LENNEI.—This is a garden hybrid between M. conspicua and M. obovata discolor, and has flowers as large as a goose's egg, of a rosy-purple colour, and produced profusely.

M. MACROPHYLLA.—North America, 1800. This species has very large leaves and flowers, larger, perhaps, than those of any other species. They are very showy, being white with a purple centre. It attains a height of 30 feet.

M. OBOVATA DISCOLOR (syn M. purpurea).—Japan, 1790. This is a small-growing, deciduous shrub, with large, dark green leaves, and Tulip-shaped flowers, that are purple on the outside and almost white within.

M. PARVIFLORA, from Japan, with creamy-white, fragrant flowers, that are globular in shape, is a very distinct and attractive species, but cannot generally be relied upon as hardy.

M. STELLATA (syn M. Halleana).—Japan, 1878. A neat, small-growing, Japanese species, of bushy habit, and quite hardy in this country. The small, white, fragrant flowers are produced abundantly, even on young plants, and as early as April. One of the most desirable and handsome of the small-growing species. M. stellata (pink variety) received an Award of Merit at the meeting of the Royal Horticultural Society on March 28, 1893. This bids fair to be really a good thing, and may best be described as a pink-flowered form of the now well-known and popular species.

M. UMBRELLA (syn M. tripetala).—Umbrella Tree. North America, 1752. A noble species, with large, deep green leaves, that are often 16 inches long. It is quite hardy around London, and produces its large, white, fragrant flowers in succession during May and June. The fruit is large and showy, and of a deep purplish-red colour.

MEDICAGO.

MEDICAGO ARBOREA.—South Europe, 1596. This species grows to the height of 6 feet or 8 feet, and produces its Pea-shaped flowers from June onwards. The leaves are broadly oval and serrated at the tips, but they vary in this respect. It is not hardy unless in warm, sheltered corners of southern England and Ireland, although it stood unharmed for many years at Kew. It succeeds best, and is less apt to receive injury, when planted in rather dry and warm soil.

MENISPERMUM.

MENISPERMUM CANADENSE.—Moonseed. North America, 1691. This shrub is principally remarkable for the large, reniform, peltate leaves, which are of value for covering pergolas, bowers and walls. The flowers are of no great account, being rather inconspicuous and paniculate. It is hardy in most places, and is worthy of culture for its graceful habit and handsome foliage.

MICROGLOSSA.

MICROGLOSSA ALBESCENS (syn Aster albescens and A. cabulicus).—Himalayas, 1842. This member of the Compositae family is a much-branched shrub, with grayish lanceolate foliage, and clusters of flowers about 6 inches in diameter, and of a bluish or mauve colour. It is a native of Nepaul, and, with the protection of a wall, perfectly hardy around London.

MITCHELLA.

MITCHELLA REPENS.—Partridge Berry. North America, 1761. A low-growing, creeping plant, having oval, persistent leaves, white flowers, and brilliant scarlet fruit. It is a neat little bog plant, resembling Fuchsia procumbens in habit, and with bunches of the brightest Cotoneaster-like fruit. For rock gardening, or planting on the margins of beds in light, peaty soil, this is one of the handsomest and most beautiful of hardy creeping shrubs.

MITRARIA.

MITRARIA COCCINEA.—Scarlet Mitre Pod. Chiloe, 1848. This is only hardy in the South of England and Ireland, and even there it requires wall protection. It is a pretty little shrub, with long, slender shoots, which, during the early part of the summer, are studded with the bright red, drooping blossoms, which are urn-shaped, and often nearly 2 inches long. It delights in damp, lumpy, peat.

MYRICA.

MYRICA ASPLENIFOLIA (syn Comptonia asplenifolia).—Sweet Fern. North America, 1714. A North American plant of somewhat straggling growth, growing to about 4 feet high, and with linear, pinnatified, sweet-smelling leaves. The flowers are of no decorative value, being small and inconspicuous, but for the fragrant leaves alone the shrub will always be prized. It grows well in peaty soil, is very hardy, and may be increased by means of offsets. This shrub is nearly allied to our native Myrica or Sweet Gale.

M. CALIFORNICA.—Californian Wax Myrtle. California, 1848. In this we have a valuable evergreen shrub that is hardy beyond a doubt, and that will thrive in the very poorest classes of soils. In appearance it somewhat resembles our native plant, but is preferable to it on account of the deep green, persistent leaves. The leaves are about 3 inches long, narrow, and produced in tufts along the branches. Unlike our native species, the Californian Wax Myrtle has no pleasant aroma to the leaves.

M. CERIFERA.—Common Candle-berry Myrtle. Canada, 1699. This is a neat little shrub, usually about 4 feet high, with oblong-lanceolate leaves, and inconspicuous catkins.

M. GALE.—Sweet Gale or Bog Myrtle. This has inconspicuous flowers, and is included here on account of the deliciously fragrant foliage, and which makes it a favourite with cultivators generally. It is a native shrub, growing from 3 feet to 4 feet high, with deciduous, linear-lanceolate leaves, and clustered catkins appearing before the leaves. A moor or bog plant, and of great value for planting by the pond or lake side, or along with the so-called American plants, for the aroma given off by the foliage.

The Myricas are all worthy of cultivation, although the flowers are inconspicuous—their neat and in most cases fragrant foliage, and adaptability to poor soil or swampy hollows, being extra recommendations.

MYRTUS.

MYRTUS COMMUNIS.—Common Myrtle. South Europe, 1597. A well-known shrub, which, unless in very favoured spots and by the sea-side, cannot survive our winters. Where it does well, and then only as a wall plant, this and its varieties are charming shrubs with neat foliage and an abundance of showy flowers. The double-flowered varieties are very handsome, but they are more suitable for glass culture than planting in the open.

M. LUMA (syn Eugenia apiculata and E. Luma).—Chili. Though sometimes seen growing out of doors, this is not to be recommended for general planting, it being best suited for greenhouse culture.

M. UGNI (syn Eugenia Ugni).—Valdivia, 1845. A small-growing, Myrtle-like shrub, that is only hardy in favoured parts of the country. It is of branching habit, with small, wiry stems, oval, coriacious leaves, and pretty pinky flowers. The edible fruit is highly ornamental, being of a pleasing ruddy tinge tinted with white. This dwarf-growing shrub wants the protection of a wall, and when so situated in warm seaside parts of the country soon forms a bush of neat and pleasing appearance.

NEILLIA.

NEILLIA OPULIFOLIA (syn Spiraea opulifolia).—Nine Bark. North America, 1690. A hardy shrub, nearly allied to Spiraea. It produces a profusion of umbel-like corymbs of pretty white flowers, that are succeeded by curious swollen membraneous purplish fruit. N. opulifolia aurea is worthy of culture, it being of free growth and distinct from the parent plant.

N. THYRSIFLORA, Nepaul, 1850, would seem to be quite as hardy as N. opulifolia, and is of more evergreen habit. The leaves are doubly serrated and three lobed, and cordate-ovate. Flowers white in spicate, thyrsoid racemes, and produced rather sparsely.

NESAEA.

NESAEA SALICIFOLIA (syn Heimia salicifolia).—Mexico, 1821. This can only be styled as half hardy, but with wall protection it forms a pretty bush often fully a yard in height. The leaves resemble those of some species of Willow, being long and narrow, while the showy yellow flowers are freely produced in August and September. It thrives best when planted in light, dry soil, and in a sheltered position.

NEVIUSA.

NEVIUSA ALABAMENSIS.—Alabama Snow Wreath. Alabama, 1879. This is a rare American shrub, with leaves reminding one of those of the Nine Bark, Neillia opulifolia, and the flowers, which are freely produced along the full length of the shoots, are white or yellowish-green, with prominent stamens of a tufted brush-like character. It is usually treated as a green-house plant, but may be seen growing and flowering freely in the open ground at Kew.

NUTTALLIA.

NUTTALLIA CERASIFORMIS.—Osoberry. California, 1848. This shrub is of great value on account of the flowers being produced in the early weeks of the year, and when flowers are few and far between. It grows from 6 feet to 10 feet high, with a thick, twiggy head, and drooping racemes of white flowers borne thickly all over the plant. Few soils come amiss to this neglected shrub, it growing and flowering freely even on poor gravelly clay, and where only a limited number of shrubs could succeed.

OLEARIA.

OLEARIA HAASTII.—New Zealand, 1872. This Composite shrub is only hardy in the milder parts of England and Ireland. It is of stiff, dwarf growth, rarely growing more than 4 feet high, but of neat and compact habit. Flowering as it does in late summer it is rendered of special value, the Daisy-like white blossoms being produced in large and flat clusters at the branch tips. The leaves are neat and of leathery texture, and being evergreen lend an additional charm to the shrub.

O. MACRODONTA (syn O. dentata), from New Zealand, 1886, is tolerably hardy, and may be seen in good form both at Kew and in the South of Ireland. The large Holly-like leaves are of a peculiar silvery-green tint above, and almost white on the under sides. Flowers white, and produced in dense heads in June and July.

O. Forsterii and O. Gunniana (syn Eurybia Gunniana) are nearly hardy species, the latter, from New Zealand, bearing a profusion of white Daisy-like flowers on dense, twiggy branches.

ONONIS.

ONONIS ARVENSIS.—Restharrow. A native undershrub of very variable size, according to the position in which it is found growing. It creeps along the ground, the shoots sending out roots as they proceed, and is usually found on dry sandy banks. The flowers when at their best are very ornamental, being bright pink, and with the standard streaked with a deeper shade. They are abundantly produced, and render the plant very conspicuous during the summer and autumn months. When planted on an old wall, and allowed to roam at will, the Restharrow is, perhaps, seen to best advantage.

OSMANTHUS.

OSMANTHUS AQUIFOLIUM ILLICIFOLIUS.—Holly-leaved Osmanthus. Japan. This is a handsome evergreen shrub, with Holly-like leaves, and not very conspicuous greenish-white flowers. It is a very desirable shrub, of which there are varieties named O.A. ilicifolius argenteo-variegatus, O.A. ilicifolius aureo-variegatus, and O.A. ilicifolius nanus, the names of which will be sufficient to define their characters.

O.A. ILICIFOLIUS MYRTIFOLIUS.—Myrtle-leaved Osmanthus. A very distinct and beautiful shrub, with unarmed leaves. It is of dwarf, compact growth, with small, sharply-pointed leaves, and inconspicuous flowers. For the front line of a shrubbery this is an invaluable shrub, its pretty leaves and neat twiggy habit making it a favourite with planters. The variety rotundifolius is seldom seen in cultivation, but being distinct in foliage from any of the others is to be recommended. They grow freely in any good garden soil, but all the better if a little peat is added at the time of planting.

OSTRYA.

OSTRYA CARPINIFOLIA (syn O. vulgaris).—Common Hop Hornbeam. South Europe, 1724. A much-branched, round-headed tree, with cordate-ovate, acuminate leaves. Both this and the following species, by reason of the resemblance between their female catkins and those of the Hop, and between their leaves and those of the Hornbeam, have acquired the very descriptive name of Hop Hornbeam. This is a large-growing tree, specimens in various parts of the country ranging in height from 50 feet to 60 feet.

O. VIRGINICA.—Virginian Hop Hornbeam. Eastern United States, 1692. Resembles the latter, but is of smaller growth, rarely exceeding 40 feet in height. They grow fairly well in almost any class of soil, and on account of the long and showy catkins are well worthy of cultivation.

OXYDENDRUM.

OXYDENDRUM ARBOREUM (syn Andromeda arborea).—Sorrel-tree. Eastern United States, 1752. Unfortunately this species is not often found under cultivation, being unsuitable generally for our climate. In some instances, however, it has done well, a specimen in the Knap Hill Nursery, Surrey, being 30 feet high, and with a dense rounded head. The flowers are very beautiful, being of a waxy white, and produced abundantly. It wants a free rich soil, and not too exposed site.

OZOTHAMNUS.

OZOTHAMNUS ROSMARINIFOLIUS.—Australia, 1827. A pretty little Australian Composite, forming a dense, twiggy shrub, with narrow, Rosemary-like leaves, and small, whitish, Aster-like flowers which resemble those of its near relative, the Olearia, and are produced so thickly that the plant looks like a sheet of white when the blooms are fully developed. It flowers in June and July. In most parts of the country it will require protection, but can be classed as fairly hardy. Cuttings root freely if placed in sandy soil in a cool frame.

PAEONIA.

PAEONIA MOUTAN.—Moutan Paeony, or Chinese Tree Paeony. China and Japan, 1789. A beautiful shrubby species introduced from China about one hundred years ago. The first of the kind introduced to England had single flowers, and the plant is figured in Andrews' Botanists' Repository (tab. 463) under the name of P. papaveracea. The flowers are white with a dark red centre. In the Botanical Magazine (tab. 2175), the same plant is figured under the name of P. Moutan var. papaveracea. This is perfectly hardy in our gardens, and is the parent of many beautiful and distinct varieties, including double and single white, pink, crimson, purple, and striped.
