Trees, shrubs or herbs, or sometimes vine-like. Leaves pinnate, 2- to many- foliolate or occasionally aphyllous, often with petiolar or rachial glands; leaflets entire, often inequilateral. Inflorescence bracteate, axillary or terminal, racemose or paniculate or the flowers rarely subsolitary. Flowers usually yellow, conspicuous; calyx with a disc-like base and 5 usually imbricate sepals; petals 5, distinct, ex- panded, often unequal; stamens 10-4, the 3 uppermost usually rudimentary or lacking, the 4 median similar, usually intermediate in size, often conspicuously rostrate; the 3 lowermost similar or dissimilar, rarely lacking, variously modified but usually rostrate, usually larger than the median stamens; anthers dehiscent by terminal or basal pores or sometimes (in addition) lateral slits, basifixed and erect; ovary sessile or stipitate, several- to many-ovulate. Legume dehiscent or sometimes indehiscent, terete or more often compressed or flattened, the seeds often horizontal, the funicle filiform to very short.
