General Information

Herbs, annual or perennial, subshrubs, or rarely shrubs. Leaves pinnate or palmate, usually sessile, 3-9-foliolate; stipules absent, or reduced to small dark glands; leaflets sessile or on very short petiolules, most species with 5 leaflets, 3 crowded at apex of leaf rachis, 2 at base; basal pair similar to apical ones or often differing in shape and stipulelike. Inflorescence an axillary, pedunculate, 1- to many-flowered umbel; peduncle with a sterile bract usually represented by a conspicuous leaf with 1-3(-5) leaflets; flower-sub­tending bracts reduced to small dark glands (rarely with a herbaceous blade) or absent; bracteoles usually absent, when rarely present then glandular. Calyx campanulate or trumpet-shaped; teeth 5, subequal or distal longer, sometimes connate into 2 lips. Corolla yel­low (often turning green in herbarium), pink, violet, brown, or white. Vexillary stamen free. Ovules numerous or several; style entire [or with a small toothlike appendage]; stigma terminal. Legume linear to ovoid, straight or incurved, terete or flattened, longitu­dinally dehiscent [indehiscent in 1 species outside China]. Seeds subglobose or lenticular, smooth, rarely verrucose.
