Engravings. L'Hérit. Stirp., Lt. 83.; Bot. Reg., t. 1985.; and our fig. 1116.


Spec. Char., &c. Leaves coriaceous, glaucescent, with a saltish, bitterish taste. Corolla white, having the throat veined with green. Stamens white. Stigma green. Nuts the form of those of Coffea arábica, convex on one side, marked by a slender furrow in the middle, obtuse at top, and perforated by two roundish holes at the base: hence it is tridentate, the first tooth from the middle of the back, the other two from the sides: sometimes, but only by abortion, 1-celled. Albumen copious, fleshy. (Don's Mill., iv. p. 480.) A shrub, a native of the south of Brazil, in woods, where it has been collected by Sello; but which was introduced from Peru by Joseph Jussieu into France, whence it was sent to this country in 1780. It grows to the height of 6 ft., and flowers in April and May. There are fine specimens of it in the Horticultural Society's

Garden, against a wall; and in the Epsom Nursery, as a bush in the open garden; from which it appears to be as hardy as Lycium europæ'um. The whole plant has a mealy white appearance; by which, and by the singular form of its leaves, it may be known at first sight from any species of Lycium. Though it has been introduced into British gardens so many years since, and was known in France in the time of Du Hamel, it is rarely met with in collections; and, though so easily propagated by suckers, it is not to be found for sale in the nurseries.

App. I. Half-hardy ligneous Plants belonging to the Order Solanaceæ.


Nicotiana glauca Grah., Bot. Mag., t. 287.; and our fig. 1118.; is a splendid suffruticose plant, which will grow to 10 ft. or 12 ft., or probably to 20 ft. or upwards, against a wall, making a fine appearance in the summer season, with its large glaucous leaves, and yellowish green flowers. A plant in the Horticultural Society's Garden has stood out since 1852; and, though its stems are occasionally cut down by the frost, yet the stool always pushes out vigorously in the spring. A plant of this species in the Chelsea Botanic Garden attained the height of 14 ft., in 1835, in the open border.

Brugmansia sanguinea Ruiz et Pav.; B. bicolor Pers., Swt. Fl. Gard., 2d ser., t. 272.; and our fig. 1117.; has an arboreous stem, which rises to the height of from 10 ft. to 20 ft. The flowers are produced from the forks of the branches. Corolla funnel-shaped, 7 in. long, green towards the base, orange yellow farther along its length. The limb 5-lobed, of a deep orange scarlet; this colour, lessened in intensity, seems to extend down the tube, until it blends with the orange



shrub, introduced in 1815, growing to the height of 3 ft., and producing its yellow flowers in abundance in June and July. It is almost hardy, having stood in the Kew Garden, against a wall, 6 years, without any protection whatever; and in various other gardens about London, where the soil is dry, as a border shrub.




THIS order, which is nearly allied to Solanaceæ, consists chiefly of herbaceous plants, the only hardy ligneous genus being Búddlea.

Spec. Char., &c. Branches tetragonal, clothed with hoary tomentum, as

well as the under
sides of the leaves.
Leaves lanceolate,


nated, petiolate. Heads of flowers globose, pedunculate. A shrub, a native of Chili, growing to the height of 12 ft. or 15 ft. in the climate of London, and producing its bright yellow globelike heads of flowers, which are fragrant, from May to July. It was introduced in 1774, and is frequent in collections. North of London, it



requires a dry sheltered situation, or to be planted against a wall. It will grow in any common soil, and is readily propagated by cuttings put in in autumn, and protected from the frost by a hand-glass. Price of plants, in the London nurseries, Is. 6d. each. A plant at Purser's Cross is 12 ft. high and 15 ft. in diameter; and it has frequently ripened seeds, from which young plants have been raised.

App. i. Half-hardy Species of Buddlea.

Buddlea salvifolia Lam.; Lantana salvifolia Lin., Jac. Sc., 1. t. 28.; is a native of the Cape of Good Hope, bearing some resemblance to the common species, but smaller in all its parts. It has been known to stand out for two or three years together against a wall, without any protection. B. paniculata Wall. is a native of Nepal, introduced in 1823, but not common in collections.

B. saligna Willd., Jacq. Sc., 1. t. 29., is a native of the Cape of Good Hope, with white flowers, which are produced in August and September.

B. crispa Royle Illust., p. 291., is said to be a highly ornamental shrub, found at moderate elevations in the Himalayas.

App. I. Half-hardy ligneous Plants of the Order Scrophulariacea.

Halleria lucida L., Bot. Mag., t. 1744., and our fig. 1125., is a shrub, a native of the Cape of Good Hope, with shining leaves, and scarlet flowers, which are produced from June to August. A plant has stood out in front of the stove at Kew since 1826.

[graphic][graphic][merged small][merged small]

Maurándya semperflorens Jacq., Bot. Mag., t. 460.; and M. Barclayàna Bot. Reg., t. 1108.; are Mexican climbers, well known for the beauty of their flowers; and which, in warm situations, grow and flower freely against a wall in the open air, and may be protected during winter; or seeds, which


they produce in abundance, may be sown early in the season in a hot-bed, and the plants brought forward in pots, and in due time turned out.

Mimulus glutinosus Willd., Bot. Mag., t. 354., is an evergreen shrub, a native of California, with rich orange-coloured flowers, which would, in all probability, thrive against a conservative wall with very little protection.

Anthocercis viscosa R. Br., Bot. Reg., t. 1624., is a native of New Holland, introduced in 1822. It is a handsome evergreen shrub, with dark green leaves, and rather numerous, large, white flowers, which are produced in May and June. It is easily propa. gated by cuttings, on which account it well deserves a place in a warm sheltered border) during the summer season, or against a conservative wall.

Calceolaria integrifolia L., Bot. Reg., t. 744.; C. rugòsa Fl. Per., Hook. Ex. Fl., 29.; and C. séssilis Hort., see our figs. 1127, 1128.; and many other suffruticose hybrids; stand through the winter, as border shrubs, in many of the warmer parts of Devonshire and Cornwall; and with due care, in the neighbourhood of London, they may be kept alive on a conservative wall.



Verónica decussata Ait., Bot. Mag., t. 242., and our figs. 1129, 1130., is an evergreen shrub, a native of the Falkland Islands, which grows to the height of 1 ft. or ft, and produces its white or bluish white flowers from June to August. It is very easily protected, either at the foot of a wall or on rockwork, and stands out without any protection in the Isle of Portland, where it grows to the height of 4 ft. or 5 ft.


Célsia landta Jac., Bot. Reg., t. 438., and our fig. 1126., is a suffruticose plant of uncertain origin, but with showy yellow flowers, which it produces from July to September. It is commonly kept in a frame, but would thrive well on conservative rockwork, in a favourable situation.

Capraria lanceolata L.; Frælínia salicifolia Bot. Mag., t. 1556.; is a native of the Cape of Good Hope, introduced in 1774. A plant has stood against the wall in the Chelsea Botanic Garden for several years; and, though it is generally klled down to the ground in winter, it has always hitherto sprung up again in spring, and made a much finer appearance than it could possibly have done in a pot.

The genera Aionsda R. et P., Angelònia H. B. et Kunth, Lophospermum Don, Rhodochiton Zucc., Nycterinia D. Don, all contain species which might be tried against a conservative wall in the south of England.

If, after perusing what is stated in this work respecting the half-hardy ligneous plants of any order or tribe, the reader will turn to the same natural order or tribe in our Hort. Brit., he will generally find a number of other species, green-house or stove plants, and suffruticose or completely ligneous, from which he may increase his selection for trial in the open air.


OF THE HARDY LIGNEOUS PLANTS OF THE ORDER LABIA CE. ALMOST the whole of the plants of this order, which are technically ligneous or suffruticose, may be more properly treated, in gardens, as herbaceous plants

than as shrubs; nevertheless, as this work would be incomplete without noticing them, we shall name some of the principal species, and refer for the remainder to our Hortus Britannicus. The best situation for a collection of ligneous Labiàceæ, is on dry rockwork.



Satureja montana L., Fl. Græc. t. 543., and our fig. 1131., is a well-known culinary herb, a native of the south of Europe, which, on dry calcareous soil, will form a neat little evergreen bush, from 1 ft. to 2 ft. in height. capitàta Willd., a native of the Levant, is equally hardy, and, indeed, appears to be only a variety of the former. There are, also, some species or varieties from Sicily, Candia, and the Ionian Islands, which are considered as frame plants, and may be tried on conservative rockwork.



Thymus vulgaris L., and
fig. 1132., forms a neat little ever-
green shrub, when kept in dry cal-
careous soil, or on rockwork: and
T. grandiflorus Hort.; T. Masti-
china L., Black., t. 134.; is a native
of Spain, with hoary, hairy calyxes.
In an arboretum where every single
species or variety is to be exhibited


by itself, such a beautiful and fragrant genus as Thymus may have a small cone or hemisphere of rockwork devoted to each species or variety. There are some half-hardy species, which might also be tried. They are not only beautiful when in flower, but are highly fragrant, and attractive to bees.

Hyssopus officinalis L., and our fig. 1133., forms an undershrub of 2 ft. in
