(J02 ARBORETUM AND FRUTICETUM. PART 111. 



C. ulbidus 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.

 f. 2.; C. hirsutus and C. suplnus Bieb. Fl. Taur. ex Stev. in Litt. s C. macrospermus 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. suplnus 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 gibber 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. serdtinus Kit in Litt. Stems ascending. Branches round, hairy. Leaflets obovate, glabrous 

 above, and rather hairy beneath. Flowers axillary, 23, pedicellate. Calyxes hairy. Native of 

 Hungary. (Dec. Prod., ii. p. 155.) 



C. pygm^us Willd. Spec., 3. p. 1127L Stem procumbent, suffVuticose. 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. pdnticus Willd. Spec., 3. p 1J20., exclusive of the synonyme of Tourn. ; C. ponticus humifusus 

 magno fibre 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. punticus, which, according to him, is allied to Adenocarpus hispanicus, 

 and has round branches, not furrowed; and obovate leaflets, not elliptic. (Dec. Prod., ii. p. 157.) 



C. cantscens Lois in N. Du Ham., 5. p. 151. The whole plant is clothed with silky hoary pubes- 

 cence. 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. africanus Lois, in N. Du Ham., 5. p. 154. ; C. africanus hirsutus angustifblius 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. procirus Link Enum., 2. p. 241. ; Spartium proc^rum 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. ; Spartium prsicum Willd. So., 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 psoraleoldes ; and, if the stamens, as is suspected, are 

 diadelphous, it is certainly referable to Indigofera. (Dec. Prod., ii. p. 157.) 



App. ii. Half-hardy Species of Cytisus. 



G.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 coun- 

 try, it is found on mountains, it is probably half-hardy. 



C. pdllidus 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 3ft., and bearing a general 

 resemblance to Genista /inifblia, of which it is probably only a variety. 



C. nubigenus Link Enum., 2. p. 240. ; Spartium nubigenum Ait. Hort. 

 Kew. t 3. p. 13. ; S. supranubium Linn. Fil. Suppl., 319. ; CyYisus fragrans 

 Lam. Diet. ; has the flowers fragrant. It is a native^of the Peak of Tene- 

 riffe, 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. bvactf.olutus Hort with racemes of golden yellow powerfully fragrant 

 flowers, C. tetragon6cladus Hort also fragrant, and C. racembsus 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 addi- 

 tions to our green-houses and conservative walls. Whenever a new species 

 of the C^tisus 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 qfCytisus. 



The seeds of a number of species of C^tisus have been collected in Teneriffe and the Canary Isles 

 by Phillip 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 al- 

 ready 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.
