Characteristics

Shrub or small tree 1.5–10 m. tall, with glabrous stems; trunk warty and knobby, with reddish brown bark.. Leaf-blades elliptic or oblong-elliptic, 4–25 cm. long, (1.1–)2–10 cm. wide, acute to shortly acuminate at the apex, rounded to cuneate at the base, entirely glabrous, with narrowly hyaline, sometimes revolute margins, coriaceous, often drying the characteristic yellow of an aluminium accumulating plant or young leaves drying purplish, often ± shining above; nodules absent; domatia present, not margined with hairs; petiole 0.5–2 cm. long, glabrous; stipules obovate, 1–1.5 cm. long, emarginate at the apex, the lobes rounded, glabrous, soon deciduous, a few hairs present on nodes inside the stipules at the base.. Flowers sweet-scented, fleshy, heterostylous, 5-merous, in much-branched panicles 6–20 cm. long; peduncle 2.5–13 cm. long, glabrous; secondary branches 0.8–1.7 cm. long, glabrous; pedicels obsolete; bracts and bracteoles small with a few cilia.. Calyx rounded-conic (subglobose in life), ± 1 mm. long, glabrous; limb cupuliform, 2–2.5 mm. long, glabrous; lobes small or obsolete.. Corolla white or? greenish yellow, glabrous outside; tube 4–6 mm. long; lobes oblong-triangular, 2–2.5(–3) mm. long, 1.2(–2) mm. wide, margined in dry state, thickened and inflexed at the apex.. Stamens with filaments 2.5–3 mm. long in short-styled flowers, 0.5–1 mm. long in long-styled flowers.. Style 3.5–4 mm. long in short-styled flowers, 6 mm. long in long-styled flowers; stigma-lobes 0.5–1 mm. long.. Drupes red, with 2 pyrenes, subglobose or ellipsoid, 6–7 mm. in diameter, glabrous, only slightly grooved even in dry state; pyrenes depressed-semiglobose, 5.5–6 mm. long, 5–5.5 mm. wide, 2.2–3 mm. thick, the dorsal face scarcely grooved.. Seeds dark, 5 mm. long and wide, 2.8 mm. thick, semiglobose, ventral face rugose, dorsal face with 3 basally joined obtuse ribs and rugose; albumen strongly ruminate.
