LEGUMINOS2E. 



the first of which consists of plants, the radicle of whose embryo 

 is curved back upon the edge of the cotyledons (f. 21 . b. e.f.) ; the 

 second, of those whose radicle and cotyledons are straight (f. 21 . i. 

 k. I. m.) ; the former is called Curvernbrice, the latter Rectembrice. 

 In the Curv&mbriee certain diversities in the structure of the calyx 

 and corolla again divide into two principal forms, one of which, 

 comprehending all the genera with papilionaceous flowers (f. 27.), 

 is called Papilionacece, and the other consisting of a very small 

 number of species with 1 or 2 petals or more, and an obscurely 

 lobed calyx, is called Snartxieee (f. 52.). The last is not sub- 

 divided, but the Papilionaceee resolve themselves into two great 

 tribes, namely, those with fleshy cotyledons (f. 21. c.) and eat- 

 able pidse called Sarculobee, and those with foliaceous cotyledons 

 (f. 21. a.f.), and seeds which are not eatable, called Pliyllblolxz, 

 each of these is divisible by three upon slight differences in the 

 fructification. In the Rectembrece two suborders, Mimosece (f. 

 53. f. 54.) and Ccesalpinece (f. 56. f. 57.), are formed upon va- 

 riations in the estivation of the calyx and corolla ; in the former 

 it is valvate, in the latter imbricated ; the first constitutes a single 

 tribe, the latter divides into three. Having thus explained the 

 principles upon which Leguminbsce is arranged, the following 

 synopsis of the genera will be intelligible. 



Synopsis of the Genera. 

 DIVISION I. 



CURVE'MBRLE. Radicle bent back upon the edge of the lobes 

 of the cotyledons in embryo (f. 21. b. e.f.). 



SUBORDER I. 



PAPILIONA'CEJE. Embryo with the radicle lying in the fissure 

 of the cotyledons (f. 21. b. e.f.). Sepals imbricate in aestivation 

 or somewhat valvate. Petals disposed in a papilionaceous man- 

 ner (f. 24. b. f. 25. b. &c.), always irregular, the upper one is 

 called a vexillum (f. 21. ;.), the two side ones wings (f. 21. o.), 

 and the lower one, which is usually composed of 2 petals, the 

 keel (f. 21. p.). Stamens inserted in the bottom of the calyx, or 

 perigynous.

 leaves and yellow flowers. 



8 PIPTA'NTHUS. Calyx 5-toothed, somewhat bilabiate at the 

 apex. Vexillum with subincurved edges. Wings involute at

 seeded. A shrub, with trifoliate leaves and yellow flowers. 



9 THERMOPSIS. Calyx campanulate, 4-5-cleft, somewhat bi- 

 labiate, convex behind. Petals nearly equal. Vexillum with 

 reflexed sides. Legume compressed, falcate or linear, many-

10 BAPTI'SIA. Calyx half 4-5-cleft, bilabiate. Petals nearly

 illum large. Keel covered by the wings. Stamens rather con-
