Description Lianas or slender shrubs or trees with scandent branches, glabrous throughout, the branches and branchlets usually opposite, sometimes alternate, slender, lenticel- late. Leaves opposite, petiolate, the petiole canaliculate. Inflorescences axillary or arising from branchlets below the leaves, solitary or aggregated, usually many- flowered, pedunculate, paniculate-corymbose or pseudocymose. Flowers herma- phrodite, in distal dichotomies or congested in clusters of 2-5 at the apex of ultimate branchlets, small, pedicellate; sepals 5, rounded or obtuse at the apex; petals 5, spreading or suberect, rounded at the apex, submembranous or thin-carnose; disc minute, forming an annular cushion below the stamens, slightly projecting, often hardly distinguishable from the ovary, carnose; stamens 3, suberect to spreading, the filaments membranous, the anthers extrorsely nutant, transversely ellipsoid, dehiscing by apical, transversal, confluent clefts; ovary depressed-3-lobed, 3-celled, the cells 2- to 8-ovulate, the ovules collateral or in superposed pairs, ascending from the inner basal angle; style very short, obtuse or minutely capitate, the stigmas obscure or minute and alternate with the stamens. Fruits several per inflorescence, of 3 capsular mericarps, these divergent, separately attached to a swollen receptacle, flattened on both surfaces, obtuse or subacute and slightly swollen at the base, sharp and entire at the margins, dehiscing along an incon- spicuous, median suture, the pericarp papyraceous or thin-coriaceous; seeds 2-8 per mericarp, the embryoniferous portion somewhat flattened, affixed by a conspicuous, membranous, basal wing.
