Abstract

Shrubs or subshrubs. Leaves distichous, margin entire; blade simple; stipules absent; indumentum absent or present on young shoots. Flowers in leaf axils or terminal on longer shoots, not forming well-circumscribed inflorescences. Flowers cream, or yellow and red, bisexual, actinomorphic, spiral, epigynous; receptacle urceolate; sepals and petals absent, but floral envelope constituting a cap consisting of one or two fused bracts. Stamens about 20–100, tetrasporangiate; filaments short, broad, anthers basifixed, introrse, opening with longitudinal slits that bifurcate at both ends; inner staminodes about 40–80 with marginal and laminal glands; stamens and staminodes basally united, forming a synandrium; carpels about 13–70, syncarpous (but spiral!), styles absent; ovules 2–11 per carpel, anatropous, apotropous, bitegmic, crassinucellar, in two series along ventral side of carpels. Fruits fleshy berries, seeds ruminated; endosperm fleshy (oily); embryo straight, small, dicotyledonous.
