Mostly perennial herbs, sappy and succulent, stemless or caulesent. stems swollen at nodes, erect, creeping or scandent. Leaves fleshy, cauline or from rhizomes or tuber, alternate, distichous, generally long-petiolate, stipulate, simple, ovate-acuminate, orbicular or pelate in outline, mostly caodate at base and often very unequal-sided or obliquely auriculate and strongly asymmetrical, entire or more or less with irregularly incised, digitately divided, laciniate, dentate or lobed margins, palmately or pinnately nerved. Stipule 2 to each leaf, free, membranaceous, often caducous, or semipersistent. Flowers monoecious, mostly in clusters of axillary cymes; peduncle axillary, divided into dichotomous cymes. staminate flowers large in number and usually opening first, actionmorphic or often zygomorphic, showy and often of bright colors, mostly pink, white or reddish; tepals 2-4, petal like, opposite, valvate, white or colored. Stamens numerous, in many whorls forming a dense capitulum; filaments free or variously connate; anther 2-locular, basifixed, continuous with filament, opening by longitudinal slits, rarely by pores; connectives mostly prolonged. Pistillate flowers with tepal more or less as on the staminate, lager, imbricate; ovary inferior, often 3-locular, rarely 2-or 4- to 5-locular, mostly 3-angular or winged, often colored, one wing often strongly developed; styles mostly as many as ovary-loculi, free or connate at base, 2-lobed or branched; stigmas prominent, oddly bent or spirally twisted like a corkscrew, papillose nearly all ovary; placentas mostly axile; ovules many in each loculus, anatropous, inserted on placentas adnate to axil of ovary, rarely parietal. Fruit mostly a capsule, loculicidal or irregularly dehiscent, unequally 3-winged, or sometimes baccate. Seeds minute and very numerous, with scanty or no endosperm; embryo straight.
