Description
|
Trees, unarmed. Leaves alternate; blades coriaceous, the primary laterals numerous, fine, rather closely spaced, often subobscure, straight (not arcuate ncar the margin). Flowers fasciculate in the axils of leaves or leaf-sc ars or solitary; sepals usually 6, infrequently 4 or 8, in 2{ whorls of (42)3(4); corolla-lobes as many as the sepals, each with a pair of dorsal ? petaloid appendages arising from the base, occasionally these fused to the lobes or lacking; staminodes usually petaloid, rarely minute or replaced by functional-stamens; stamens as many as corolla-lobes or rarely twice as many (morphologically 2 whorls), typically at- tached to the corolla at the juncture of the tube and lobes; ovary often pubescent, 6 to 14-celled, the ovules affixed laterally. Fruit 1 to several-seeded, fleshy; seed compressed, the scar rather elongate, lateral or basilateral (but equalling or sur- passing the middle of the seed), more or less linear, the endosperm copious.
