Scrambling woody vines, monoecious or dioecious, glabrous throughout; branchlets subtended by imbricate bud-scales. Leaves simple, alternate, spirally arranged or congested at the laterally terminal brachlets, estipulate. Flowers unisexual, mostly solitary and axillary to leaves on lateral and terminal branchlets or rarely aggregated on branches, pedicellate, hypogynous, actinomorphic; pedicels with minute bracteoles; perianth of 5-17 tepals, the outermost green abaxially, more showy inward and adaxially. Staminate flowers with many stamens, variously aggregated; anthers 4-sporangiate, the 2 thecae lateral, dehiscing longitudinally; filaments short, basally fused to a cylindrical to globose torus, the connective slightly swollen and broaden, pollen usually 6-colpate with 3 colpi converging at the distal pole. Pistillate flowers with many subascending carpels, the carpels 1-loculed, narrowed basally and fused to a cylindrical to globose torus; style short, the stigma papillate; ovary ovoid to obovoid; ovules 2-5, anatropus; fruits sessile, baccate, on a globose or elongate torus; seeds 1-5, laterally flattened, reniform or ovoid, the testa smooth or rugulate, the endosperm copious, oily, the embryo small.

Two genera, about 50 species; except a single American species (Schisandra glabra), all others indigenous to eastern and southeastern Asia and Malaysia.
