Characteristics

Unarmed apparently glabrous tree 4–7 m. tall; outer bark peeling in several conspicuous, glistening, copper-coloured, translucent, fragile, layered sheets from the green under-bark; slash red outside, white inside, exudate very white, gummy, odourless; twigs rather slender, often ± 2 mm. in diameter; buds reddish.. Leaves coriaceous, olive-green when dry, apparently always 3-foliolate (but leafy long-shoots not yet seen), apparently glabrous but minute glandular hairs 0.05–0.1 mm. long present on petioles and petiolules; petiole channelled, 20–55 mm.; lateral petiolules 2–3 mm.; central petiolule 2–10 mm. long; leaflets entire, ovate-rhombic, the laterals rounded at the base but usually with a narrow wing-like, often asymmetric, extension into the petiolule, the central broadly cuneate and also narrowly drawn out into the petiolule; all leaflets acuminate, the acumen up to 2 cm. long, 3–5 mm. wide near its middle, acute; lateral leaflets up to 5 cm. long × 3 cm. wide, the central up to 7 by 14 cm.; lateral veins 3–5 on each side, slightly prominent above and beneath, ultimate vein network dark, visible but not prominent.. Male flowers unknown.. Fruiting panicles minutely glandular pubescent, borne among the leaves, 1–3 cm. long (shorter than the petioles), each with (1–)2(–3) drupes; pedicels 5–8 mm. long. Calyx 1.5 mm. long, the reflexed triangular lobes as long as the tube; staminodes 1.5 mm. long; style subpersistent on young fruits, cylindrical, 1 mm. long; stigma capitate.. Drupe flattened, asymmetric ellipsoid, slightly apiculate, measuring when dry 10.5 × 8 (2 + 3.5) mm., after boiling 12 × 10 × (2.5 + 4) mm.; pericarp 2-valved; pseudaril with 4 broadly triangular irregular lobes almost as long as the stone which is smooth with distinct sutural ridges, a very faintly marked germination shield, minute apical slits, a fertile locule with a markedly protuberant smooth hump above its middle and an almost flat gently convex sterile locule, 9.5 × 7 × (1.5 + 3) mm..
