Lianas, the branches stout, terete, cinereous, the branchlets usually opposite, elongate, slender. Leaves opposite or subopposite, petiolate. Inflorescences axillary, pedunculate, cymose, dichotomously branched. Flowers hermaphrodite, paired or ternate at the apex of ultimate inflorescence-branchlets or solitary in distal di-chotomies, pedicellate; sepals 5, erosulous or ciliolate at the margins; petals 5, imbricate, spreading, serrate at the margins; disc continuous, suberect, short-cylindric, usually flattened or grooved on the margin, carnose; stamens 3, suberect, the filaments ligulate, the anthers broadly reniform, dehiscing by apical, trans-versal, confluent clefts; ovary depressed-3-lobed, 3-celled, the cells 8-to 14-ovulate, the ovules imbricate in a mass attached to the inner basal angle; style stout, carnose, the stigmas 3, minute, often obscure, opposite the stamens. Fruits of 3 flattened, capsular mericarps, these spreading, firmly connate proximally, convex on both surfaces, sharp and entire at the margin, inconspicuously carinate and dehiscing along a median suture, the pericarp coriaceous, flabellate-costate without, smooth within; seeds 8-14 per mericarp, closely imbricate, affixed by a basal, membranous wing.
