spermum. ORD. Leguminose. A small genus (three 
species) of slender, erect, greenhouse under-shrnbs, natives 
of South Africa, with yellow, nodding flowers, and digitately 
trifoliolate leaves. D. lebeckioides has been introduced, but 
is probably no longer grown. 
DICHLAMYDEOUS. Furnished with both calyx and
