 incurved. Stamens diadelphous or nearly so. Style beardless. Pod linear, flat, 

 several-seeded (some few of them rarely partly subterranean and fleshy or de- 

 formed). Low, mostly prostrate or twining perennial herbs. Leaflets usually 

 3, stipellate. Flowers in somewhat interrupted or knotty racemes, purplish ; in

 short and flat, 2-valved. Usually twining or trailing perennial herbs, pinnatelv 

 3-foliolate, or with a single leaflet, not stipellate. Flowers yellow, racemose or
