Abstract
Much-branched, evergreen, dioecious shrubs. Leaves small, decussate, subsessile, exstipulate, entire. Plants pubescent with short uniseriate hairs. Male flowers in axillary capitate clusters, shortly pedunculate or sessile, subtended by a small bract; female solitary, pendulous on short recurved peduncle, subtended by 2 large bracts and prophylls, rarely in few-flowered racemes. Flowers actinomorphic, hypogynous, apetalous, without nectaries; male: sepals (4)5(6), strongly imbricate, fimbriate; stamens free, 8–16, with short, stout filaments, inserted ± distantly on the flat receptacle; anthers basifixed, extrorse, dithecal, tetrasporangiate, longitudinally dehiscent, pistillode absent; female: much larger, sepals (4)5(6), foliaceous, strongly imbricate, acuminate, ± ventricose to accrescent below, persisting; ovary syncarpous, 3(4)-carpellate, placentation apical-axile; stylodia 3, subulate, long, reflexed, caducous; ovules 1(2) per locule, anatropous. Fruit an obtusely triangular capsule, partly enclosed by the enlarged sepals, loculicidally 3-valved, usually 1-seeded by abortion, rarely 2–3-seeded; seeds brownish-black; endosperm scanty or absent; cotyledons thick, fleshy, containing liquid wax.
