Flowers a, actinomorphic; sepals usually 5, occasionally reduced to 4 or up to 10; petals usually the same number as the sepals, mostly imbricate in the bud; stamens 5 to so, hypogynous, often surrounded by one to several rows of staminodia, the anthers basifixed, dehiscing poricidally or longitudinally; pistil solitary, the ovary superior, often borne on an enlarged torus or gynophore, the carpels and locules 2-5, the placentae axile or parietal, intrusive, the ovules oo (rarely 1 per locule), occasionally alate, the style usually slender and unbranched, the stigmatic surface often indistinguishable or the stigmas radial and conspicuous. Fruits either baccate, the carpels separating as distinct cocci or druplets on an enlarged torus, or capsular and dehiscing septicid- ally, or rarely nut-like and indehiscent (extra-Panama), the seeds occasionally conspicuously winged.
