Characteristics

Shrub or tree, 2–10 m. tall; young branches square, often somewhat winged at corners, glabrous or rarely puberulous; older branches with fawn or greyish bark.. Leaf-blades narrowly to broadly elliptic or less often obovate, 3–10.5 cm. long, 1.3–5 cm. wide, acute or more often gradually acuminate at apex, acute or occasionally obtuse at base, coriaceous, very shiny above, glabrous; lateral nerves in 5 main pairs; tertiary nerves obscure to apparent, coarsely reticulate; domatia absent or inconspicuous; petioles 2–3 mm. long, glabrous; stipules 3–7(–10) mm. long, triangular at base, terminating in a linear keeled decurrent lobe.. Flowers both 4-and 5-merous, borne in sessile to subsessile 7–50-flowered umbellate cymes; peduncle, if present, not exceeding 3 mm. long; pedicels 2–7 mm. long, pubescent or rarely glabrescent; bracteoles inconspicuous.. Calyx-tube 1–2 mm. long, glabrous or puberulous; limb reduced to a shortly toothed rim.. Corolla whitish; tube 2–2.5 mm. long, with a ring of deflexed hairs above mid-point inside; lobes oblong-lanceolate, 3–3.5 mm. long, 1.5 mm. wide, acute.. Anthers narrowly oblong, reflexed.. Style 4–6 mm. long; stigmatic knob 1.25–1.5 mm. long.. Disk glabrous.. Fruit black when mature, somewhat wider than long, 5–6.5 mm. long, 6–7.5 mm. wide, apex slightly prominent to scarcely indented, pyrene ± ellipsoid, 6 mm. long, 4–4.5 mm. wide, with a wide groove beneath point of attachment, rugulose to bullate.
