Wings usually free from the keel. Pod glabrous or silky-hairy. 



Flowers small, in dense umbels or heads along the" branches of a leafy 

 panicle, each umbel almost enclosed in a 2-foliolate leaf. Pod-articles 2, 

 nearly orbicular (Sect. PhyUodium). — 8. D. pulcheUum. 



Flowers in leafless racemes. Pedicels short crowded. Pod-articles 2, 

 nearly orbicular. Leaflets digitate or nearly so. (Sect. Dicerma.). — 1. D. 

 biartioulatum. 



Wings adhering to slight lateral protuberances or membranous appendages 

 of the keel. 



Flowers in racemes or panicles. Ovules several, rarely 2 onlj. Pod of

 or slightly indented between the seeds. (Heteroloma) .
