    Lianas or scandent shrubs. Leaves alternate, usually scabrous, pubescent with simple or stellate hairs more or less incrusted with silica, the petioles often canalic- ulate and narrowly alate. Inflorescences axillary or terminal, paniculiform, many- flowered. Flowers unisexual, actinomorphic, the pistillate with many apparently sterile hypogynous stamens; sepals usually 5, persistent, more or less equal or the outer slightly smaller; petals 2-5, caducous; stamens 50-200, multiseriate, persistent, the filaments free to basally fused, filiform, the anthers longitudinally dehiscent, the outermost frequently sterile, 2-thecate, the thecae nearly parallel to basally divergent, about half sunken into the dilated connective; carpels 1-5, pyriform, free, 1-loculed, the ovules 2-12, more or less erect on 2, seldom 3, ventral placentas, the styles filiform, exceeding the stamens in pistillate flowers, the stigmas capitate, frequently somewhat emarginate. Follicles 1-5, pyriform, dry, dehiscing along the ventral suture, the seeds 1-4, smooth, arillate, the aril lacerate, unilateral, about half enveloping the seed, the embryo small, straight.
