Description Shrubs, sometimes scandent, or trees, sometimes functionally dioecious, stri- gose to softly pubescent, the hairs simple, uniseriate, or stellate. Leaves mostly alternate, rarely subopposite, simple, mostly homomorphic, sometimes dimorphic, petiolate. Inflorescences cymes, very irregular, paniculate and open, spike-like, or rarely densely glomerate, axillary or terminal, the bracts generally absent. Flowers perfect and homomorphic or functionally unisexual and slightly heteromorphic, actinomorphic, ? sessile; calyx of 5 connate sepals, tubular or ? campanulate, sometimes costate, densely strigose to softly pubescent, sometimes with resinous dots when young, 5-lobed or splitting irregularly and 2-4-lobed; corolla of 5(-12) connate petals, funnelform to salverform, marcescent or falling soon after anthesis, sparsely strigose to glabrous, white to cream, 5(-12)-lobed, the lobes oblong and conspicuous, almost as broad as long, or shallow and obscure; stamens as many as the corolla lobes, functional, or reduced and abortive, epipetalous, borne on the corolla throat, alternate, the filaments. sometimes fimbriolate and/or hooked near the base, the anthers dehiscing longitudinally, introrse; ovary 4-loculed, functional or reduced and abortive, unlobed, the ovules 1-4, usually only one developing, style slender, elongate, twice bifid, the stigmas 4 and capitate or clavate. Fruit usually drupaceous, unlobed, the exocarp dry or mucilaginous; seed usually 1.
