Mag., t. 1927., and our fig. 337.), the Vulnerària Bárba Jovis 337 Lam., and Bárba Javis argyrophylla Mænch, is an evergreen shrub, which grows to the height of 8 ft.; a native of Spain, Barbary, the Levant, and Italy, on rocks; and it has been cultivated in frames in England since 1640. The leaves are pinnate, and the flowers pale yellow; the whole plant having a silvery appearance, whence it derives the names of Jupiter's beard, and the silver bush, The elegance of this shrub did not escape the ancients; and Pliny mentions its beauty; adding, that it dislikes water, and that it makes a very elegant ornament for gardens when clipped into a round shape. It is also mentioned by Dioscorides as good for healing wounds, by the application of its leaves. It is one of the finest shrubs that can be planted against a conservative wall. It will grow in any light soil, and is easily propagated by cuttings, or by seeds, which are sometimes ripened against a south wall.
A. cylisőides L. (Barrel. Icon., t. 1182.) a native of Spain, and the south of France, was introduced in 1731. It grows to the height of 2 ft.,
and forms a neat little frame shrub, almost hardy in the neighbourhood of London.
A. Hermanniæ L. (Bot. Mag., t. 2576.) is a native of Corsica, Crete, and Palestine. It forms a spiny shrub, with pubescent leaves, and yellow flowers, which appear from April till July. It was introduced in 1789, and grows to the height of from 2 ft. to 3 ft. There is a plant of it which has been two years in the open border in the Kew Garden, without any protection whatever. A. Aspá. lathi Dec., Spártium créticum Desf., (Bot. Cab., t. 1169.) resembles the preceding species, and may possibly be only a variety of it.
A. erinàcea L. (Bul. Mag., t. 676.) grows about 1 ft. high, and has rushy branches, and bluish purple flowers.
A. Genistæ Dufour., A. spléndens Willd., A. i ndica Lour., and A. sericea Lag., are species which have not yet been introduced. A. heterophylla L. is a procumbent species, a native of Portugal and Spain, introduced in 1768, but now, it is believed, lost.
Medicago L. is a genus chiefly consisting of herbaceous plants; but there are one or two shrubs
338 or undershrubs belonging to it that may be considered half-hardy. The species are mostly natives of the south of Europe, the Levant, and the north of Africa. M. arborea L. (N. Du Ham., 4. t. 44., and our fig. 338.), the lucerne en arbre of the French, is a native of Italy, where it grows to the height of 6 ft. or 8 ft., and flowers from May to November. It has been known to stand out 5 or 6 years in dry borders, without any protection, and to attain a considerable size when trained against a wall. In the Chelsea Botanic Garden there is a plant 11 ft. high, with a stem 64 in. in diameter; there is also one of considerable size in the Kew Garden ; and there was formerly a large one trained against a wall in the gardens at Syon.
Melildtus arbdrea Castagne in Litt. (Dec. Prod., 2. p. 187., Don's Mill., 2. p. 177.) is a shrub, with trifoliolate leaves, and stipules adhering to the petiole; cultivated about Constantinople, where it grows 15 ft. high, with a trunk 3 in. in diameter. It was introduced into this country in the year 1826, and produces its white flowers from July to September ; but it is seldom to be met with in collections. It is, doubtless, as hardy as Medicago arborea.
Lotus L. contains two or three species, somewhat ligneous, that might deserve trial against a conservative wall. They are natives of the south of Europe, the north of Africa, and the Cape of Good Hope. Lòtus créticus L. (Cav. Icon., 2. p. 44. t. 156.) is a native of Syria, Candia, and Spain. It is a slender shrub, not higher than 1 ft. or 2 ft., producing yellow flowers from June to September. L. anthyllöides Vent. Malm., p. 92. t. 92., is a native of the Cape of Good Hope, with yellow flowers.' £. atropurpàreus Dec. has dark purple flowers. L. jacobæ'us L. (Bot. Mag., t. 79., and our fig. 339.) is a native of the Cape De Verde Islands, and has been in culture since 1714. It grows to the height of 3 ft., with a dark purple
corolla, almost black,
and 339 the standard yellowish. There is a variety with yellow flowers. This, and all the other species of Lotus, flower a great part of the year, and are, consequently, all very desirable for low conservative walls, of from 3 ft. to 5 ft. in height. L. Broussonétii L. and L. spectábilis are splendid
Teneriffe species, introduced by P. B. Webb, Esq., and to be procured in the Milford Nursery
Carmichaelia australis R. Br. (Bot. Reg., 912.) is a New Zealand shrub, with flat branches, and bluish flowers. The leaves, which are trifoliolate or pinnate, drop off soon after they are expanded. This shrub grows to the height of 6 ft. or 7 ft., flowering profusely from May to September. From its native country, there can be no doubt but it is as hardy as Medicago arbòrea, and that it would thrive equally well against a conservative wall.
Psordlea L. is a genus of herbaceous and suffruticose species, 64 of which have been described : they are natives of the south of Europe, Africa, and North America, and some few of the ligneous species are half-hardy.
P. bitumindsa'L. (Lam. IV., t. 614. £. 1.) is a native of the south of Europe, in exposed places, and has been an inhabitant of our green-houses since 1670. It is common in the rocks between Genoa and
Nice, where it is seldom seen higher than 2 ft. or 3 ft. ;
one in the garden of the Horticultural Society has stood 340 against a wall since 1831, without protection : it grows
rapidly, and appears quite hardy. P. pubescens Balb.
(Bot. Reg., t. 968.) is a native of Peru, with bright blue flowers. P. plicata Delil. is a native of Upper Egypt ; and 'P. obtusifolia Dec. is a native of the Cape of Good Hope ; but neither has yet been introduced. There are some other ligneous species mentioned in Don's Miller as not being sufficiently known.
Indigófera L. is a genus including above 140 species, among which is I. tinctdria, which produces the common indigo of the shops. Some of the species are ligneous, and natives of Africa or Asia ; but, as they are generally of low growth, they are not very desirable for planting out against a low wall. I. denudata Jacq. (Bot. Cab.,
t. 500., and our fig. 342.) has red flowers, streaked with dark lines. It grows to the height of 2 ft., and flowers from May till July. 1. ama na Ait
. (Bot. Reg., t. 300.) grows to the height of 3 ft., and has dark red flowers, which are produced in May and June 1. atropurpurea Hamilt. is a native
of Nepal, introduced in 1816. It grows to the height of 5 ft. or 6 ft., and produces its dark shining purple fowers in July and August. 1. australis Willd. (Bot. Cab., t. 149., and our fig. 343.) is a native of New Holland. It grows to the height of 4 ft., and has rose-coloured flowers. 1. sylvática Sieb. (Bot. Mag., t. 3000.), the I. angulata of Bot. Reg., t. 258., is also a native of New Holland, and grows to the height of 8 ft. It is a very showy plant, producing its flowers from May to June. Various other green-house species, already introduced, will be found enumerated in our Hortus Britannicus ; and many, not introduced, are described in Don's Miller.
Swainsonia Salisb. is a genus of elegant New Holland shrubs, all beautiful, and well deserving a place against a low conservative wall in a mild locality. S. galegifolia R. Br. (Bot. Mag., t. 792., and 344
our fig. 344.) grows to the height of 3ft.; and produces red flowers from June to August. There ie a variety of this with white flowers, figured in Bot. Reg., t. 994. S. coronillafolia Salisb. (Bot. Mag., t. 1725.) and S. lessertiæfðlia Dec. are rather herbaceous than ligneous ; but their flowers are large and handsome, and, when kept in a frame during winter, and turned out in the borders in spring, they make a fine appearance.
Lessértia Dec. contains some undershrubs, one or two of which have been introduced. L. fruticosa Lindl. (Bot. Reg., t. 970., and our fig. 345.) is a native of the Cape of Good Hope, which grows to the height of 3 ft., and produces its purple flowers in July and August.
Sutherlandia frutéscens R. Br., Colùtea frutéscens L. (Bot. Mag., t. 181.; and our fig. 346.) is a hoary shrub, with large, elegant, scarlet, showy flowers, a native of th, Cape of Good Hope. It grows to the height of 3 fte or 4 ft., flowering from June to August; and, in very. mild winters, it will stand in the borders without protection. S. microphylla Burch. is another Cape species, which has not yet been introduced.

CORONI'LLA Neck. THE CORONILLA. Lin. Syst. Diadélphia Decándria.
Derivation. From corona, a crown, in reference to the disposition of the flowers in crowns, or umbels, at the tops of the peduncles.
Description, fc. The ligneous species are hardy or half-hardy, deciduous or subevergreen, shrubs, natives of the south of Europe or Asia, with imparipinnate leaves, and flowers on pedicels disposed in umbels placed on axillary peduncles. They are all highly ornamental, and most of them produce seeds in England, by which, or by cuttings, they are easily propagated.

brous. Its leaves are attended by minute stipules, and have 5–7 obovate leaflets. Its flowers are yellow, disposed 3 upon a peduncle. The claws of the petals are thrice as long as the calyx. The legume is rather cylindrical than compressed, and its joints separate slowly and unobviously, but they do se- 347 parate. It is spontaneous in hedges and thickets of middle and southern Europe, and of Tauria. (Dec. Prod., ii. p. 309.) Introduced in 1596, and flowering from April to June. Height 10ft. Before the flowers are expanded, the corolla is partly red externally, mostly so towards the tips of the petals; and the mingling of the yellow flowers, with flower buds more or less red, and the elegant foliage, render this hardy shrub a very
desirable one for its beauty. Perhaps it Hourishes most in a sunny sheltered situation, and a dry soil. It bears clipping pretty well, and would form a beautiful hedge. Plants, in the London nurseries, are 9d. each ; at Bollwyller, 50 cents; and at New York, 374 cents.

t. 383. 1. 2.; and our fig. 348. Spec. Char., &c. Shrubby, glabrous. Branches rush-like,
round, bearing but few leaves; the latter are attended by minute stipules, and have 3–7 leaflets, that are linear oblong, obtuse, and rather fleshy; the lowest leaflets being rather distant from the base of the petiole. The flowers are yellow, 5—7 in an umbel. The claws of the petals are scarcely longer than the calyx. The legume is rather compressed, and its joints separate obviously. (Dec. Prod., ii. p. 309.). The whole plant is very glaucous. Native of the south of France, and introduced in 1756. It grows to the
346 height of 2 ft. or 3 ft., and produces its bright yellow flowers in June and July. It deserves a place in collections, on account of the singularity of its rush-like slender branches, which, like those of Spártium júnceum, are partly destitute of leaves.
App. i. Half-hardy ligneous Species of Coronilla. The half-hardy species of this genus are eminently beautiful, and some of them have been known to live for years in the open border, in a dry soil, in the neighbourhood of London. Against a wall, they will live with very little protection, producing their beautiful yellow flowers early in spring (one species, C. stipularis, in March); and continuing fowering throughout the summer. As they produce abundance of seeds, a stock of plants may always be kept in pots or cold-pits, and turned out into the open borders, where they will flower freely throughout the summer; and, if they should be killed during the succeeding winter, the loss can easily be supplied,
