Tree; young shoots glabrous, dark brown to greyish, becoming finely cracked and scaling, sometimes lenticellate. Leaves spaced, spirally arranged, 5.5-15(-l 9) × 2.5-6 cm, elliptic to oblanceolate, apex acute to narrowly attenuate, base narrowly attenuate, coriaceous, glabrous, lower surface usually minutely punctate; venation eucamptodromous, marginal vein present, midrib slightly raised on the upper surface, secondary veins 7-11 pairs, convergent, arcuate; intersecondaries moderate to long; tertiaries conspicuous, parallel to the secondaries and reticulate. Petiole 0.5-1.8 cm long, slightly channelled, glabrous. Fascicles 2-20 flowered, axillary and in the axils of fallen leaves. Pedicel 2-6 mm long, with sparse minute appressed hairs or glabrous. Flowers unisexual and bisexual (functionally male?; plant apparently monoecious or dioecious. Sepals 4-5, 1-1.5 mm long, broadly ovate or suborbicular, apex rounded, sparsely appressed puberulous on both surfaces, or glabrous. Corolla 1.75-2.25 mm long, tube equalling or slightly longer than the lobes; lobes 4-5, ovate to suborbicular, apex obtuse, rounded or truncate, glabrous. Stamens 4-5, fixed at the top of the corolla tube; filaments ca. 0.1 mm long, glabrous; anthers 0.3-0.5 mm long, inflexed, ovate to lanceolate, glabrous; stamens absent in female flowers. Staminodes 4-5,0.3-0.4 mm long, ovate to subulate, glabrous, reduced to a vestige in female flowers. Disk absent. Ovary flattened (ovoid in female flowers), bilocular, puberulous, style 0.4-0.5 mm long after anthesis, included, glabrous; style-head simple. Fruit 2.5-6 cm long, ellipsoid or obovoid, apex rounded, base acute to obtuse or rounded, hard-skinned, smooth, glabrous. Seed 2-3.5 cm long, ellipsoid, laterally compressed, rounded at both ends, testa shining, nearly always wrinkled or verrucose, rarely smooth, 0.3-1 mm thick; scar full-length, adaxial, 2-4 mm wide; embryo with plano-convex, free cotyledons, radicle extending to the surface; endosperm absent. Field characters. Tree to 35 m high and 40 cm diam., buttressed to 2 m high, slash exuding copious milky latex. Flowers greenish-yellow, fruit ripening orange-yellow. The cotyledons are reported to be purple (FDBG 4106). Flowering and fruiting throughout the year. The fruits are eaten by the monkey Cebus apella (Foster & Janson 8279, Peru).
