f A species not sufficiently known. 



14 C. FRUTICOSA (Bess. cat. hort. crem. p. 116.) said to be 

 allied to C. arborescens, but differs in the flowers being larger 

 and solitary, and in the young legumes being red. J? . S. 

 Native of the Russian empire. Perhaps Robinia Mongolica of 

 Fisch. and R. speciosa of Swartz ex Besser. 



Shrubby Caragana. Shrub 2 to 3 feet. 



Cult. All the species of this genus are well adapted for 

 shrubberies. They are usually propagated by layers and by 

 seeds. The species are all deciduous.

 and ctvopov, dendron, a tree ; in reference to the shrub, which 

 grows in dry naked salt fields by the river Irtis, in Siberia). Fisch. 

 in litt. D. C. legum. mem. vi. prod. 2. p. 269. Halodendron, 

 D. C. mem. ined. in soc. phys. gen. march, 1824. but not of 

 Petit Thouars.

 panulate, with 5 short teeth. Keel obtuse, straightish. Wings 

 very acute and auricled. Stamens diadelphous, about equal in 

 length. Style filiform, glabrous. Stigma terminal. Legume 

 stipitate, inflated, bladdery, hard, ovate, and few-seeded, de-

 peduncles 2-rlowered. *j . H. Native of Siberia, in dry salt fields 

 at the river Irtis, and of Iberia. Robinia halodendron, Lin. fil. 

 suppl. 330. Pall. fl. ross. t. 36. itin. 2. t. W. ed gall, append, 

 no. 360. t. 83. f. 1. Caragana argentea, Lam. in Pall, ed gall. 

 1. c. This is an elegant silky shrub, it thrives well in the 

 gardens, but seldom or never flowers, probably from the want of 

 the saline principle in which it naturally grows. 



Var. a, vulgftre (D. C. prod. 2. p. 269.) leaves between 

 hoary and silvery ; vexillum length of keel. Sims, bot. mag. 

 1016. 



Var. ft, brachysema (D. C. 1. c.) leaves hoary and silvery ; 

 vexillum one half shorter than the wings and keel ; style short. 

 Perhaps only a monster raised in gardens. 



Silvery Salt-tree. Fl. May, Jul. Clt. 1779. Sh. 4 to 6 ft. 



2 H. SUBVIRE'SCENS ; leaves greenish ; vexillum length of 



carina ; pedicels 3-flowered. t; . H. Native of Siberia, in 

 salt fields. Robinia triflora, Lher. stirp. nov. 162. H. argen- 

 teum /3, subvirescens, D. C. prod. 2. p. 169. 



Greenish Salt-tree. Fl. May, Ju. Clt. 1779. Sh. 4 to 6 ft. 



Cult. See last genus for culture and propagation. They 

 are elegant deciduous shrubs, and deserve to be cultivated in 

 gardens. 



CXXII. DIPHY'SA (from cig, dis, twice, and </>vira, pliysa, 

 a bladder ; in reference to the legume, which is furnished with 

 a large membranous bladder on each side of the legume, rising 

 from the sutures). Jacq. amer. 208. Schreb. gen. no. 1104. 

 Lam. ill. t. 605. D. C. prod. 2. p. 269. 



LIN. SYST. Diadelphia, Decandria. Calyx 5-cleft, 2 supe- 

 rior lobes roundish, 3 lower ones acute. Vexillum obovate- 

 oblong, reflexed ; wings flat. Keel sickle-shaped. Stamens 

 diadelphous. Legume linear, compressed, furnished on both 

 sides with a large membranous bladder, which rises from the 

 sutures, and are therefore opposite each other, 1-celled, 5-6- 

 seeded. A small unarmed tree, with impari-pinnate leaves, 

 composed of 5 pairs of leaflets and an odd one, axillary 2-3- 

 flowered peduncles, and yellow flowers. The place which this 

 genus should occupy in the order is very doubtful, in conse- 

 quence of the structure of the legume being imperfectly known. 



1 D. CARTHAGENE'NSIS (Jacq. amer. 208. t. 180. f. 51.) 

 T? . S. Native of Carthagena, in bushy places, where it is called 

 Fivaseca.

 straight at the base, but glabrous incurved at the apex. Stigma 

 terminal. Legume sessile, oblong, somewhat cylindrical, mu- 

 cronate, 1-celled ; valves concave, beset with soft hairs, as well 

 as with stiff, glandular bristles, mixed. A deciduous shrub, with 

 lanceolate stipulas, impari-pinnate leaves, and axillary pedunculate 

 racemes of yellow flowers. This genus differs from Cytisus in 

 the stamens being diadelphous, and in the pinnate leaves.

Cult. This shrub is well adapted for the front of shrubberies, 

 and is increased by layers or by seeds. Being rather tender it 

 should be protected by a mat in winter.

 putate ; the shrubs are said to die if the branches are lopped off. 

 KoXourta is also the name of a plant in Theophrastus). R. Br. in
