plants were generically distinct; the calyx in Leptosema being bibracteate, - 
and composed of two nearly equal lips, the upper very slightly bifid, the vex. - 
illum scarcely unguiculate, the wings* about equal in length to the keel, 
and the carinal suture of the legume distinctly inflexed. The inflorescence is 
likewise very different in the two plants: in Leptosema the flowers are di- 
stinctly pedicellate, alternate, and disposed in a densely-crowded raceme, 
rather. than a capitulum; whereas in Jansonia they are perfectly sessile, 
arranged in a verticillate manner round a common axis, which is slightly 
prolonged beyond the point whence the flowers spring in the form of a short 
mucro. ` | | |
