sac narrow, scrotiform ; the longer filameiits obliquely obovate-dilated above, the shorter scarcely 
dilat< {l ; style about equaling the capsule; seeds rugose-pitted.

Flowers sealten d ali>ng the diffuse branches, and usually with filiform sometimes twisted and 
prehensile hraneidets from the same axils ; leaflets petiided, mostly exceeding the flowers ; calyx
