shrubs, with small stipulas, impari-pinnate leaves, and axillary 

 few-flowered racemes, which are a little shorter than the leaves. 



1 C. ARBORE'SCENS (Lin. spec. 1045.) leaflets elliptic, retuse ; 

 peduncles usually bearing about 6 flowers; gibbosities on the 

 vexillum short ; legume closed. T? . H. Native of middle and 

 south Europe, in hedges and bushy places, on Mount Vesuvius, 

 even in the ascent to the crater, where hardly any other veget- 

 able is to be found. D. C. astr. no. 1. Duham. arbr. ed. 

 nov. 1. t. 22. Curt. bot. mag. t. 81. C. hirsiita, Roth. fl. 

 germ. 1. p. 305. Flowers yellow. The C, arborcscens of 

 Burm. fl. cap. 22. is probably a species of Tephrbsia. The 

 leaves are recommended as answering all the purposes of senna, 

 and Allioni gives particular directions for the preparation of 

 them. A larger dose seems to be required to produce the same 

 effect. The seeds to the quantity of a drachm or two excite 

 vomiting.

 Shrub 6 to 10 feet. 



2 C. CRUE'NTA (Ait. hort. kew. 3. p. 55.) leaflets ob- 

 ovate, emarginate, glaucous ; peduncles 4 or 5-flowered ; vex- 

 illum with small, obtuse gibbosities ; legume gaping at the 

 apex. Tj . H. Native of the islands in the Archipelago, 

 Iberia, and the Levant. D. C. astr. no. 3. Lher. stirp. nov. 2.

 t. 119. C. humilis, Scop. Flowers of a reddish-copper colour, 

 but with the vexillum having a yellow spot at the base. This 

 species differs from the foregoing in the smaller different co- 

 loured flowers, in the wings being shorter than the keel, and 

 in the pod being open at the apex.

 5 to 10 feet. 



t Species not sufficiently known. 



6 C. ? jESCHiNOMENOiDES (Scop, insub. 3. p. 22. t. 12.) plant 

 herbaceous ; leaflets lanceolate, obtuse, glabrous, acuminated by 

 the nerve. I/ . ? G. Native of the Bahama Islands. Perhaps 

 a species of Pictetia. 



jEschinomene-like Bladder-Senna. PI. 2 feet. 



7 C. AMERICA'NA (Mill. diet. no. 5.) shrubby ; leaves with 

 3 pairs of oval leaflets ; peduncles 2-3-flowered ; legumes com- 

 pressed, fj . S. Native of Vera Cruz. Perhaps a species of 

 Ccesalp'mia. Flowers yellow. Pluk. aim. 111. t. 165. f. 3. 



American Bladder-Senna. Shrub 6 to 8 feet. 

 Cult. The species of Bladder-Senna are proper for shrub- 

 beries, as they flower in great profusion, and continue in flower 



the most of the season. They thrive in any common soil, and 

 are increased by seeds, which ripen in abundance, or by cuttings, 

 planted in the autumn. The two last species require to be 

 sheltered in a greenhouse. 



CXXV. SPHyEROPHY'SA(from o-^cupa, spltaira, a sphere, 

 and iftvaa, plii/sa, a bladder ; in reference to the shape of the 

 legumes, which are spherical and bladdery). D. C. legum. 

 mem. vi. prod. 2. p. 270. Pluica species of Pallas. 



LIN. SYST. Diadelphia, Decdndria. Calyx 5-toothed. Vex- 

 illum flat. Carina obtuse. Stamens diadelphous. Style bearded 

 lengthwise. Legume stipitate, inflated, spherical, hardish, 1- 

 celled, mucronated by the style. Oriental perennial herbs, with 

 impari-pinnate leaves, small stipulas, and axillary, elongated 

 racemes of red flowers. 



1 S. SA'LSULA (D. C. prod. 2. p. 271.) stem erect, rather 

 hoary ; leaves with 6 or 7 pairs of oblong, ovate leaflets, which 

 are glabrous above, but rather hoary beneath from adpressed 

 bristly hairs. If.. H. Native of Dahuria, in salt fields, about 

 Lake Tarei. Phaca salsula, Pall. itin. 4. t. 9. f. 1 and 2. ed. 

 gall, append, no. 387- t. 88. f. 1 and 2. Lin. fil. suppl. 336. 

 Coliitea Dahurica, Spreng. syst. 3. p. 242. Flowers very red, 

 almost like those of a species of Lalhyrus. 



Salt Sphaerophysa. PI. | to 1 foot. 



2 S. CA'SPICA (D. C. prod. 2. p. 271.) stems erect, and are 

 as well as the leaves clothed with adpressed pubescence ; leaves 

 with 8 pairs of oval, obtuse, mucronate leaflets. Tf.. H. Na- 

 tive of the plains between Caucasus and the Caspian Sea. 

 Colutea Caspica, Bieb. fl. taur. suppl. 1429. Phaca salsula, 

 Bieb. casp. 210. Flowers of a dirty pale-purple colour, and 

 marked with more obscure veins. Perhaps only a variety of 

 the first, according to Steven in litt. 



Caspian Sphserophysa. Fl. Jul. Aug. Clt. 1818. PI. 1| ft. 



Cull. The species of this genus succeed in common garden 

 soil, or in pots in a mixture of loam and peat ; they are very 

 difficult to preserve in gardens on account of the want of that 

 saline principle in which they grow in the places of their natural 

 growth ; and in order to preserve them in the gardens, they 

 require to be watered with salted water occasionally. They are 

 increased by seeds, which occasionally ripen in this country. 



CXXVI. SWAINSO'NIA (in honour of Isaac Swainson, 

 F.R.S. F.L.S. who was a great cultivator of plants about the

 tanical Garden, Mr. Biggs, was gardener to Mr. Swainson for 

 many years). Salisb. par. no. 28. R. Br. in hort. kew. ed. 2.
