 one or many pairs of leaflets, and with the common petiole end- 

 ing in a bristle. Flowers of various hues.

 lobes shortest. Style broad-spatulate, villous at the apex. Le- 

 gume oblong, many-seeded. Erect herbs, with abruptly-pin-

TRIBE V. 



PHASEOLE.K. Corolla papilionaceous (f. 47. c. f. 48. 6.). Sta- 

 mens monadelphous (f. 47. g.\ .but usually diadelphous (f. 48. 

 e.f.), that is, 9 joined together, and 1 free. Legume many- 

 seeded (f. 49. e.), dehiscent, with a cellular transverse membrane 

 between each seed, usually subdivided, but not articulated. Radicle 

 bent in above the fissure of the lobes of the cotyledons (f. 21. e.f.'). 

 Cotyledons not changing by germination (f. 21. c.), but grow into 

 thick leaves, and when above the earth they are usually exserted 

 beyond the spermaderm. Primordial leaves opposite, the rest 

 with the leaflets usually pinnately, rarely -palmately disposed.

 delphous. Legume linear, compressed, many-seeded. Twin- 

 ing slender herbs, suffruticose at the base, with trifoliate leaves, 

 and purple flowers.

 form, many-seeded. A prostrate herb, with trifoliate leaves, 

 and sulphur-coloured flowers. 



180 TERA'MNUS. Calyx bilabiate, upper lip longest and bifid, 

 lower one 3-parted. Keel small. Stamens monadelphous, 5 

 alternate ones sterile. Stigma sessile, capitate. Legume linear, 

 compressed, 2-valved, many-seeded. Twining subshrubs, with
