Tree to 36 m tall, to 46 cm dbh; buttresses absent or up to 0.3 m high, spreading for 0.3 m, 7 cm thick; copious white latex present in trunk and branches although also reported as absent from trunk. Bark grey, yellowish grey, grey-brown or brown, smooth or vertically finely fissured or pustular; wood yellowish or pale ochre. Branchlets glabrous, not lenticellate. Leaves: petiole 9-30 mm long, glabrous; blade subcoriaceous, elliptic, oblong or slightly obovate, 3.7-30 by 1.5-10 cm, 1.8-4.8 times as long as wide, apex short to long acuminate with a blunt tip, base cuneate, 39-60 pairs of secondary veins, fairly straight, anastomosing into an intramarginal vein close to margin, mostly somewhat obscure (and hard to accurately count), tertiary venation obscure or weakly parallel to secondary veins. Inflorescence 1.5-24 cm long; peduncle 0-5.5 cm long, glabrous; pedicels 0-11 mm long, flowers mostly subsessile, glabrous. Sepals ovate, 0.9-1.8 by 1.1-1.4 mm, 0.7-1 times as long as wide, apex rounded, glabrous, not ciliate. Corolla white or tube pinkish brown to orange with pale yellow or pale green lobes; tube 6.5-13 by 0.9-1.6 mm, 6.7-8.5 times as long as sepals, 1.1-1.7 times as long as lobes, glabrous outside, densely pubescent below stamens inside; lobes 4-7 by 1.5-2.5 mm, 2.6-3.8 times as long as wide, narrowly falcate, apex acuminate, glabrous outside and inside. Stamens inserted at 4.7-7 mm from corolla base which is 0.5-0.7 of tube length; filament 0.5-0.7 mm long; anthers 1.6-1.7 by 0.4-0.5 mm, 3.2-4.2 times as long as wide. Ovary 0.7-0.9 mm high, glabrous; style 3.4-5.5 mm long; style head 0.5-0.8 mm long. Fruit red or black, 2.1-7 by 0.9-1.9 cm, ellipsoid, often somewhat curved. Seeds 17-21 by 4-7 by 4.5-5 mm.
