Characteristics

Evergreen trees (in Panama). Leaves alternate or subverticillate, the blades penninerved. Inflorescence usually of numerous axillary or subterminal panicles, frequently subsessile (in Panama), pubescent, with persistent or deciduous bracts, often many-flowered. Flowers perfect, usually fairly conspicuous, sessile or pedunculate. Perianth-tube none, or so shallow as to appear lacking. Perianth-lobes often spreading, frequently conspicuously unequal, pubescent, usually per-sistent.' Stamens of all three series fertile (in Panama), with pubescent filaments; anthers 4-celled (in Panama), the cells in 2 planes, the bases of the 2 upper cells laterally tangential to the apices of the 2 lower cells; cells of the two outer series introrse, the filaments long and sometimes pubescent; those of the inner series extrorse or the 2 upper cells may be lateral and the 2 lower extrorse, with the fila-ments distinctly biglandular. Staminodia usually large, conspicuous, subcordate and pubescent, with the stipes of varying length, or occasionally ligulate. Ovary subglobose or ovoid, pubescent or glabrous, sometimes constricted at the base or slightly stipitate. Style usually filiform, usually longer than the ovary, and oc-casionally pubescent. Stigma inconspicuous, discoid or conspicuous and triangu-larly peltate. Fruit small, globose or large, fleshy, pear-shaped, edible, usually glabrous, entirely or almost entirely exserted at maturity, and subtended by per-sistent or occasionally deciduous perianth-lobes.
More
Evergreen trees or shrubs. Leaves papery to thickly leathery, pinninerved, ± pubescent. Cymose panicle axillary or subterminal, composed of pedunculate cymes or rarely subumbels, bracteate and bracteolate. Flowers bisexual, pedicellate. Perianth tube short; perianth lobes 6, subequal or outer 3 smaller, hairy, dilated after anthesis, caducous or persistent. Fertile stamens 9, in 3 whorls; filaments filiform, complanate, pilose, those of 3rd whorl each with 2 glands at base, others glandless; anthers 4-celled, cells introrse in 1st and 2nd whorls, all extrorse or upper 2 cells lateral and lower 2 cells extrorse in 3rd whorl. Staminodes 3, of innermost whorl, sagittate-cordate, stalked; stalk pilose. Ovary ovoid; style slender, hairy; stigma discoid. Drupe fleshy, small and globose, or large and ovoid or pear-shaped; fruit stalk ± dilated and fleshy, or terete.
Shrubs to medium-sized trees , evergreen. Bark reddish brown, thin, fissured. Leaves alternate, aromatic. Leaf blade pinnately veined; surfaces pubescent, especially abaxially, becoming glabrescent with age; domatia absent. Inflorescence appearing when mature leaves are present, axillary, flowers in pedunculate, compound cymes. Flowers bisexual; tepals persistent, yellowish, pubescent, outer tepals slightly shorter than inner; stamens 9, anthers 4-locular, 4-valved, anthers of outer 6 stamens introrse, anthers of inner 3 latrorse; staminodes 3, sagittate; ovary nearly globose. Drupe dark blue to black, nearly globose, borne on pedicel with tepals persistent at base; cupule absent. x = 12.
Shrubs or trees, evergreen. Leaves alternate, simple, lamina without domatia. Flowers in axillary or subterminal panicles, bisexual, 3-merous, pedicellate. Tepals 6, subequal or outer 3 lobes slightly shorter than inner 3, spreading to dilated, pubescent, caducous or sometimes persistent in fruit. Fertile stamens 9 in 3 whorls, or if 6, stamens of whorl III staminodial, inner 3 stamens with 2 glands at base; anthers usually 4-locular; staminodes 3, sagittate-cordate, usually large. Ovary ovoid to nearly globose, style filiform. Fruit a drupe, obovoid to globose, small to large and fleshy, with one large seed; receptacle not enlarged in fruit.
Fls perfect; inner series of tepals evidently larger than the outer; fertile stamens 9, in 3 series, the filaments of the inner series each with a pair of basilateral glands; fourth series of stamens represented by staminodes; fr subtended by the persistent, somewhat accrescent tepals; evergreen trees or tall shrubs. 200, mainly trop.
