Description:
Genus Description - Tree, dioecious, terrestrial, usually with stilt-roots; internodes (mostly) hollow; sap watery, turning black at exposure to the air. Leaves in spirals; lamina simple, peltate, radially veined and incised; petiole usually with one or two patches of dense indumentum of various trichomes (trichilia) at the base; stipules large, connate, fully amplexicaul, leaving circular scars. Inflorescences axillary, pedunculate digitate clusters of spikes, sometimes 1 spike, (usually) enclosed by a spathe until anthesis. Flowers unisexual, sessile (or short-pedicellate); tepals 2, rarely 3, mostly entirely connate, forming a tubular perianth with a narrow aperture; stamens 2, rarely 3, free; ovary free, stigma penicillate to peltate. Fruit a small achene, often tuberculate, fully enclosed by a fleshy perianth; seed with endosperm; embryo small, with flat cotyledons.
