App. i. Hardy Species of Cytisus not yet introduced.

Though we believe that by far the greater number of the cytisuses described by botanists are mere varieties, and that some of the sorts are mere names copied by one botanist after another, an unavoidable practice in the progress of science; yet, we deem it advisable to add the following descriptions, that the plants may, if possible, be brought together, and studied in the same garden.

C. arboreus Dec.; Spártium arboreum Desf. Atl., 2. p. 131. t. 177.; Genista péndula Poir. Voy., 2. p. 208. Branches striated and glabrous. Leaves petiolated; leaflets obovate, clothed with fine pubescence beneath. Flowers axillary, aggregate, pedicellate, and nodding. Pods clothed with closely pressed silky down. A shrub, 8 ft. to 10ft. high, with a trunk about the thickness of a man's arm. (Dec. Prod., ii. p. 154.) Found in valleys near Algiers, by Desfontaines.

C. Weldeni Visiani, Pl. Dalm. ex Bot. Zeit., Jan. 1830, p. 52. Upright. Leaves stalked, and disposed in threes; leaflets elliptic, entire, wedge-shaped at the base, and obtuse at the apex, smooth. Flowers in terminal racemes, stalked, pyramidal, and straight. Pedicels hairy. Calyxes campanulate, S-lobed; lobes edged with down. Corolla glabrous, but the keel clothed with silky hairs. Pod glabrous and pointed. An upright-growing shrub, from 2 ft. to 4 ft. high; a native of Dalmatia, in woods and on mounts. The flowers are yellow and fragrant. (Don's Mill., ii. p. 155., adapted.)

C. albidus Dec. Stems erect. Branches round, spreading, and rather glabrous. Leaflets oblong, pubescent beneath, as well as the calyxes. Flowers white, axillary, usually in threes, footstalked. Calyx with both lips entire. Ovary pubescent. A native of the south of Europe and north of Africa. (Dec. Prod., ii. 155.)

C. biflorus L'Hérít. Stirp., 184., Ait. Hort. Kew., 3. p. 52., Waldst. et Kit. Hung., 2. p. 166. N. Du Ham., 5. t. 45. f. 2.; C. supinus Jacq. Fl. Austr., 1. t. 20.; C. hirsutus Gmel. Sib., 4. p. 17. t. 6. f. 2.; C. hirsutus and C. supinus Bieb. Fl. Taur. ex Stev. in Litt.; C. macrospérmus Bess in Litt. Stems diffuse. Branches round, and, as well as the leaves, rather downy. Leaflets oblong-lanceolate. Flowers on short peduncles, axillary, and usually in pairs. Calyxes and pods clothed with close silky down. A native of Austria, Pannonia, Podolia, Tauria, and Siberia. (Dec. Prod., ii. p. 155.) The names of C. hirsutus and C. supinus appear to have been confused together, and both applied by botanists, not only to this plant, but to others. (See p. 599.)

Varieties.

C. b. 2 glaber Lin. Fil. Suppl., 325., has the branches and leaves glabrous; and the leaflets obovate. (Ibid.)

C. b. 3 subspinescens Dec. has the branches rather hoary, more diffuse, somewhat spinescent at the apex. Native of Naples and Hungary. (Ibid.)

C. serótinus Kit. in Litt. Stems ascending. Branches round, hairy. above, and rather hairy beneath. Flowers axillary, 2-3, pedicellate. Hungary. (Dec. Prod., ii. p. 155.)

Leaflets obovate, glabrous
Calyxes hairy. Native of

C. pygmaeus Willd. Spec., 3. p. 1127 Stem procumbent, suffruticose. Leaves petiolate, 3-leafleted; leaflets oblong-lanceolate, silky. Flowers usually at the ends of the branches. Pods oblong, and hairy. A native of Galicia (Dec. Prod., ii. p. 156.)

C. ponticus Willd. Spec., 3. p. 1120., exclusive of the synonyme of Tourn.; C. ponticus humifusus mágno flore Tourn. Cor., 44; has ascending furrowed branches, which are, like the leaves, pubescent. Leaves with three elliptic obtuse leaflets. Racemes of flowers erect and terminal. Calyxes villous. A shrub, a native of Pontus, as is implied by the specific name. Willdenow, however, gives quite a dif. ferent description of C. ponticus, which, according to him, is allied to Adenocarpus hispánicus, and has round branches, not furrowed; and obovate leaflets, not elliptic. (Dec. Prod., ii. p. 157.)

C. canescens Lois in N. Du Ham., 5. p. 151. The whole plant is clothed with silky hoary pubescence. Leaves trifoliolate; leaflets linear-oblong. Racemes few-flowered and terminal. Calyxes short, campanulate, canescent, 5-toothed. Country and legumes unknown. (Dec. Prod., ii. p. 157.) There are several plants bearing this name at Syon, but they do not appear to be the same as the species here described.

C. africànus Lois. in N. Du Ham., 5. p. 154.; C. africanus hirsutus angustifolius Tourn. Inst., 648. Branches erect, hairy. Leaves trifoliolate, with petioles; leaflets linear and pilose. Flowers stalked, in terminal umbels. Calyx hairy, hardly shorter than the corolla. A native of the north of Africa. This plant is said to be allied to Adenocarpus. (Dec. Prod., ii. p. 157.)

C. procèrus Link Enum., 2. p. 241.; Spártium procèrum Willd. Enum., 742. Branches round and striated. Leaves lanceolate and downy. Flowers solitary and axillary. Pods hairy. A shrub, a native of Portugal. (Dec. Prod., ii. p. 157.)

C.? persicus Burm. Fl. Ind., p. 163. t. 51. f. 1.; Spártium pérsicum Willd. Sp., 3. p. 931.; has the branches upright and spreading: both the branches and the leaves are finely pubescent, Leaves trifoliolate, with footstalks; leaflets linear, those in the middle being twice the length of the others. Racemes elongated and loose-flowered, opposite the leaves. Ovary villous. A shrub, a native of Persia, with nearly the habit of Indigofera psoraleöldes; and, if the stamens, as is suspected, are diadelphous, it is certainly referable to Indigófera. (Dec. Prod., ii. p. 157.)

App. ii. Half-hardy Species of Cytisus.

C. proliferus L., Dec. Prod., 2. p. 155. Don's Mill., 2. p. 155., Bot. Reg., t. 121. Bot. Cab., t. 761. and our fig. 294., is a Teneriffe shrub, with white flowers, cultivated in green-houses since 1769, and flowering in April and May. It grows to the height of from 4 ft. to 6 ft.; and, as, in its native country, it is found on mountains, it is probably half-hardy.

C. pallidus Poir., Dec. Prod., 2. p. 157., Don's Mill., 2. p. 157., is a native of the Canaries, growing to the height of 2 ft. or 3 ft., and bearing a general resemblance to Genista linifolia, of which it is probably only a variety.

C. nubigenus Link. Enum., 2. p. 240.; Spártium nubigenum Ait. Hort. Kew., 3. p. 13.; S. supranùbíum Linn. Fil. Suppl., 319.; Cytisus fragrans Lam. Dict.; has the flowers fragrant. It is a native of the Peak of Teneriffe, and was introduced by P. B. Webb, Esq. It is in the nursery of Messrs. Young, at Epsom, and flowered with them in May, 1835.

C. bracteolatus Hort. with racemes of golden yellow powerfully fragrant flowers, C. tetragonocladus Hort. also fragrant, and C. racemòsus Hort., are all Canary and Teneriffe species, which have been introduced by Mr. Webb, and have flowered in the nursery of Messrs. Young and Penny, at Milford, near Godalming. The Canary Isles appear to be rich in species of this genus; and as most of the kinds brought from that country are not only very handsome, but fragrant, they will probably prove valuable additions to our green-houses and conservative walls. Whenever a new species of the Cytisus is introduced from the warmer parts of the old world, it ought to be tried first in a green-house, or in a cold-pit or frame. It will soon, in all probability, ripen seeds, from which plants may be raised, and tried either at the base of a conservative wall, or on a bank of dry sandy soil, covered with large stones.

App. iii. Anticipated hardy and half-hardy Species of Cytisus.

The seeds of a number of species of Cytisus have been collected in Teneriffe and the Canary Isles, by Philip Barker Webb, Esq., and sent by him to the Milford Nursery, where plants have been raised from them. Among these there will, no doubt, be some undescribed species, among numbers already known and recorded; but, if care be not taken to identify the latter, it is probable that the whole will, as is usually the case, be described as new; and thus additional names will be introduced into this genus, which, in our opinion, is already sufficiently confused.

Lin. Syst. Monadélphia

Identification. Dec. Fl. Fr. Supp., 549.; Lég. Mém., 6.; Prod, 2. p. 158.; Don's Mill, 2. p. 157. Derivation. From adën, a gland, and karpos, fruit; in reference to the legumes being beset with pedicellate glands.

Description, &c. Shrubs, having very divergent branches; trifoliolate leaves, that have petiolar stipules, folded leaflets, and are usually grouped; and yellow flowers upon bracteolate pedicels, and disposed in terminal racemes.

Mongiana, in the kingdom of Naples. A shrub, 4 ft.
high, in cultivation in British gardens; but the year of
its introduction is unknown. It produces yellow flow-
ers from May to July. This is a very handsome spe-
cies, and one that is much admired for its fine terminal
spikes of flowers, which, in favourable seasons, and in
a dry soil, ripen abundance of seeds.

App. i. Half-hardy Species of Adenocarpus.

A. frankeniöldes Chois., Dec. Prod., 2. p. 158.; Genista viscosa Willd.; is a native of Teneriffe, on declivities 500 ft. above the level of the sea. Introduced in 1815, and flowering from April to July. It is commonly kept in frames; but, in a dry, airy, and yet sheltered situation, it will doubtles stand the open air. It is usually confounded in gardens with A. foliolòsus; from which it differs in having a glandular calyx.

A. folioldsus Dec., Cytisus folioldsus Ait., is a native of the Great Canary Island. Introduced in 1629; and a very old inhabitant of cold-pits and frames; flowering from May to July.

GENUS X.

ONO'NIS L. THE RESTHARROW. Lin. Syst. Monadélphia Decandria. Identification. Lin. Gen., No. 863.; Lam. Ill., t. 616.; Dec. Prod., 2. p. 158.; Don's Mill., 2. p. 158. Synonymes. Anònis and Natrix Manch Meth., 157. and 158.; Arrête-bœuf, or Bugrane, Fr.; Hanechel, Ger.

Derivation. Said to be from onos, an ass; because only asses would feed upon so prickly a plant. Restharrow is a corruption of arrest, that is, stop, harrow; from the long and deeply seated roots opposing a serious impediment to the plough or harrow.

Description. Suffruticose plants, with, mostly, trifoliolate leaves; and axillary flowers, that in some are pedicelled, and in some sessile; and yellow, purplish, and red, or, rarely, white. The peduncle is, in many instances, furnished with an awn, which is the petiole of an abortive floral leaf. (Dec. Prod., ii. p. 158.) Natives of Europe and Africa. Most of the species we have enumerated may be treated as herbaceous plants; but, being technically suffruticose, we considered it proper not to omit them. They are well adapted for rockwork or flower-borders, on account of their lively flowers, some of which are red, or reddish purple; colours not frequently met with in the ligneous Leguminàceæ, by far the greater part of which have yellow flowers. They are readily propagated by seeds or by division, and will grow in any soil that is tolerably dry. According to Pliny and Dioscorides, the shoots of Onònis are eaten pickled in brine, and the leaves are applied to ulcers. In modern times, it is considered to be slightly aperient and diuretic.

1. O. FRUTICO SA L. The shrubby Restharrow.

Identification. Lin. Sp., 1010.; Dec. Prod., 2. p. 167.; Don's Mill., 2. p. 160. Engravings. N. Du Ham., 1. t. 58.; Mill. Icon., t. 36.; Bot. Mag., t. $17.; and our fig. 298. Spec. Char., &c. Shrubby. Leaves trifoliolate. Leaflets sessile, lanceolate, serrated. Stipules connate into one, sheathing, and 4-awned; and, in the uppermost parts of the plant, occupying the places of leaves which are absent. Pedicels 3-flowered, disposed in a raceme. (Dec. Prod., ii. p. 161.)
