 Du Ham., 5. t. 45. f. 2. ; C. supmus Jacg^ Fl. Austr., 1. t. 20. ; C. hirsiitus Gmel. Sib., 4. p. 17. t. 6.

 Flowers on short peduncles, axillary, and usually in pairs. Calyxes and pods clothed with close 

 silky down. A native of Austria, J'annonia, I'odolia, Tauria, and Siberia. (Dec. Prod., ii. p. 155.) 

 The names of C. hirsTitus and C. supiniis appear to have been confused together, and both applied 

 by botanists, not only to this plant, but to others. (See p. 5!jy.) 

 yaricties. 



C.b. 2 glilber Lin. Fil. Suppl., 325., has the branches and leaves glabrous; and the leaflets 



obovate. (Ibid.) 

 C. b. 3 subspiiiilscciis Dec. has the branches rather hoary, more diffUse, somewhat spinescent 

 at the apex. Native of Najilcs and Hung.nry. (Ibid.) 



C. serdtiniis Kit. in h'M. Stems ascending. Branches round, hairy. Leaflets obovate, glabrous 

 above, and rather hairy beneath. Flowers axillary, 2 — 3, pedicellate. Calyxes hairy. Native of 

 Hungary. (Dec. Prod., ii. p. 15.i.) 



C. pygtnte'us Willd. Spec, 3. p. 112a Stem procumbent, suffruticose. Leaves petiolate, 3-lcafleted ; 

 leaflets oblong-lanceolate, silky. F'lowers usually at the ends of the branches. Pods oblong, and 

 hairy. A native of Galicia. (Dec. Prod., ii. p. 15ii.) 



C. pdnticus Willd. Spec, .3. p 1120., exclusive of the synonyme of Tourn. ; C. ponticus huniifiisus 

 m&gno flbre Tourn. Cor., 44 ; has ascending furrowed branches, which are, like the leaves, pubescent. 

 Leaves with three elliptic obtuse leaflets. Uacemcs of flowers erect and terminal. Calyxes villous. 

 A shrub, a native of Pontus, asis implied by the specific name. Willdenow, however, gives quite adif. 

 ferent description of C. puiiticus, which, according to him, is allied to Adenocarpus hispunicus, 

 and has round branches, not furrowed ; and obovate leaflets, not elliptic. (Dec. Prod., ii. p. 1,57.) 



C. caii^scens ho\s 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, ranescent, ,5.toothed. Country and legumes unknown. (Dec. Prorf., ii. p. 157.) 

 There are several pLmts bearing this name at Syon, but they do not appear to be the same as the 

 si>ecies here describe<l. 



C. africiiiius Lois, in N. Du Ham., 5. p. Ilyi. ; C. africJlnus hirsiitus angustifblins Tovrn. Inxf., 

 648. Branches erect, hairy. Leaves trifoliolate, with petioles ; leaflets linear and pilo.se. 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. 157.1 



C. procerus Link Enum., 2. p. 241. ; 5partium proctrum JfW/d. 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. f pirsicus \iyxxm. FL Ind., p. 16.3. t. 51. f I. ; .Spartium pt'rsicum Willd. .So., 3. p. 931. ; has the 

 branches upright and spreading: both the branches and the leaves arc finely pubescent. Leaves 

 trifoliolate, with footstalks ; leaflets linear, those in the middle being twice the length of the others. 

 Racemes elongated and loose-flowcred, opposite the leaves. Ovary villous. A shrub, a native of 

 Persia, with nearly the habit of Indigofcra psoralcoldcs ; 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 Ci/tisus. 



C. proliferus L., Dec. Prod., 2. p. 155. Don's Mill., 2. p. 155., Bot. Keg., 

 t. 121. Bot. Cab., t. 761. and out Jig. 2<H., is a Tenerifle shrub, with white 

 flowers, cultivated in green-houses since 1709, and flowering in April and 

 May. It grows to the height of from 4 ft. to fi It. ; and, as, in its native coun- 

 try, it is found on mountains, it is i)robably half-hardy. 



C. pdllidus Poir., Dec. Prod., 2. p. I.i7., 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 /inilt)lia, of which it is probably only a variety. 



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

 Kew., 3. p. 13. ; S. sujjranijbium Li7in. Fil. Suppl., 319. ; Cytisus frigrans 

 Lnm. 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. bracteolutus Hort. with racemes of golden yellow powerfully fragrant 

 flowers, C. tetragonocladus Hort also fragrant, and C. racetnusus Hort., 

 are all Canary and Tenerifle species, which have been introduced by Mr. 

 Webb, and have flowered in the nursery of Messrs. Voung 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 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 TenerifTe and the Canary Isle? 

 by Philip Barker Webb, Esq., and sent by him to the Milford Nursery, where plants have been raisetf 

 from them. Among these there will, no doubt, be some undescribed species among ninnbers 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.
