Inflorescences terminal or axillary racemes or panicles, usually numerous flowered; bracts and bracteoles usually small, caducous, rarely persistent. Flowers small. Calyx campanulate, 5-toothed; teeth unequal, rarely subequal, lowest teeth usually largest, upper pair usually wider than others and partially connate. Corolla white, pale green, or rarely purple; petals clawed; standard ovate, oblong, or orbicular; wing-petals with base cuneate, truncate, or sagittate; keel-petals often boat-shaped, ± united above. Stamens 10 or 9, monadelphous, usually united in an open sheath, or diadelphous and then either in 2 bundles of 5 or 9 united and 1 free; anthers erect, small, dehiscent by short apical slits. Ovary stipitate; ovules few; style usually incurved, long or short; stigma terminal, small. Fruit an indehiscent pod: types: a) strongly flattened, translucent, raised over the seeds (samaroid), b) thicker, ± leathery, often with lenticels, c) thick, ± woody, b+c) when more than 1 seed develops, pods lomented; the seeds of b/c are usually not visible from outside; seeds reniform, compressed, radicle inflexed.
