Description Annual or perennial herbs, often much branched and clambering, the stems somewhat resilient and occasionally suffruticose below. Leaves opposite, petiolate or sessile and somewhat perfoliate, exstipulate, in Central America rather broad and membranaceous. Flowers in few-flowered dichasial cymes or less frequently solitary in the axils of slightly reduced leaves. Sepals 4-5, not connate. Petals 4-5, rarely absent, white, deeply 2-cleft. Stamens 4-10; anthers versatile, 2-celled, the flattened hypogynous filaments connate below forming a brief glandular disk. Ovary superior, carpels 2-4, with as many filiform styles free to the base; ovules 4-many, camnpylotropous on basal, central or free central placentae. Capsule deeply or shallowly dehiscing into as many 2-cleft or rarely entire valves as there are styles; seeds 4-many, cochleate, smooth or tuberculate, estrophiolate, the embryo curved about the perisperm.
