Description:
Family Description - Fls perfect, slightly to evidently perigynous; sep mostly 5, ± connate into a lobed, often bilabiate tube; cor typically papilionaceous and consisting of 5 pet, the uppermost one (the standard or banner) external to the others and usually the largest; rarely, as in Centrosema and Clitoria, the fl resupinate, with the banner lowermost; 2 lateral pet, called wings, similar inter se and distinct or sometimes lightly adherent in a small area to the keel; 2 lowermost pet innermost, similar inter se, mostly connate distally to form a keel enfolding the stamens and pistil; seldom (Amorpha) only the banner present, the other pet suppressed; stamens (5–)10, most often 9 of the filaments connate into an open sheath around the pistil, the 10th (uppermost) one partly or wholly separate from the other 9 (stamens then said to be diadelphous), or less often all the stamens connate by their filaments to form a closed (or adaxially split) sheath (stamens then said to be monadelphous), or (Aeschynomene) the stamens diadelphous and 5 + 5, the sheath cleft above and below, or the filaments sometimes all distinct; pistil 1, simple; fr a legume, typically dry and dehiscent on both sutures, but sometimes indehiscent and even jointed, rarely fleshy; embryo large, the short hypocotyl-radicle typically bent back against the thickened cotyledons; endosperm mostly wanting or very scanty; herbs or less often woody plants, with alternate, stipulate, pinnately or less often palmately compound (or trifoliolate), seldom unifoliolate or simple lvs that typically have a basal pulvinus; fls borne in racemes or spikes or heads or seldom in panicles, often large and showy. 440/12,000.
