Abstract
Terrestrial dioecious shrubs or small trees, much branched, partially pubescent. Leaves (sub)opposite, simple, ovate-oblong, obtuse, short-petiolate, without stipules. Inflorescence subtended by two leaves, axillary, in 1–7-flowered congested racemes or dichasia, often reduced to only 1–2 flowers. Flowers bisexual, but functionally unisexual, hypogynous, 5(6)-merous; corolla sympetalous, imbricate. Stamens 5(6), inserted in middle of corolla tube alternating with corolla lobes; filaments free; anthers free, basifixed, longitudinally dehiscent, orientation introrse to extrorse, 2- or 4-celled; functionally female flowers with stamens but without viable pollen.Ovary 1-celled, stipitate, with nectariferous disk at base of ovary in female flowers; placentas 2, parietal; ovules 2–4, in two basal-parietal pairs, one on each side; in functionally male flowers the ovary is smaller and there is no nectary disc, style,or stigma; style elongate, deciduous, twice dichotomously divided into four slender branches; stigma apical. Capsule bivalved, with 1–4 seeds. Seeds with tuft of hairs (coma) on chalazal end.
