Abstract

Twining woody vines, or rarely straight-stemmed arborescent shrubs, evergreen or deciduous, mostly glabrous. Buds perulate. Leaves alternate, palmately or seldom pinnately compound, or trifoliolate with multiple articulations (very rarely simple); stipules usually wanting. The plants monoecious or dioecious, rarely polygamous. Inflorescences racemose or paniculate, often drooping, originating from scaly axillary buds; flowers regular, cyclic, hypogynous, trimerous, usually unisexual by abortion, with a small (rarely enlarged and fleshy) receptacle; sepals 3–8, usually 3 + 3, commonly petaloid, imbricate or the outer valvate; petals 3 + 3, smaller than the sepals, nectariferous, or wanting; male flowers with (3−) 6(−8) stamens, the filaments free or connate into a tube, the anthers free, tetrasporangiate and dithecal, extrorsely dehiscent by longitudinal slits, the often massive connectives sometimes with elongated apices, pistillodes sometimes present; female flowers with 3 (or 6–12) distinct, soon divergent carpels in 1–5 whorls of 3, rarely with numerous spiral carpels, and with or without 6 small staminodes; carpels with a sessile or subsessile stigma; stigma wet, not papillate; ovules numerous (seldom few to one) and laminar or submarginal (if solitary then subapical and pendulous), and anatropous or hemitropous, bitegmic, and crassinucellar.
