Description
|
Trees or shrubs. Leaves opposite, petiolate; blades simple or pinnately com- pound; leaflets serrate; venation pinnate; stipules and stipels usually present. In- florescences terminal or in the axils of the upper leaves, paniculate or thyrsiform. Flowers complete, bisexual and actinomorphic; sepals 5, free, unequal, imbricate; petals 5, free, unequal, imbricate in bud, inserted on or below a hypogynous crenate or lobed disc; stamens 5, arising between the lobes of the disc, alternate with the petals, the filaments complanate, the anthers 2-celled, dehiscing longi- tudinally; ovary superior, entire or lobed, 3-locular, 3-carpellate, sessile, the placentation axile, the ovules few, anatropous, the styles 3, free or united, the stigmas capitate. Fruit a berry; seeds with straight embryo and fleshy endosperm. Turpinia is a genus with probably fewer than 10 species. A single variable species occurs in Panama, and 2 or 3 other taxa occur also in Central America, though all may be only subspecifically distinct.
