Tree to 1.8 m tall. Branchlets glabrous, not lenticellate, weakly angled. Leaves: petiole 5-12 mm long, glabrous; blade subcoriaceous to coriaceous, elliptic or oblong, 7.5-21 by 2.8-8.7 cm, 2-4.1 times as long as wide, apex caudate or more rarely long acuminate, in both cases with a blunt tip, base acute to cuneate, glabrous above and beneath, secondary veins 11-27 pairs with 4-11 mm spacing, 55-80° from midrib. Inflorescence often many times branched near the base with short thick branches that appear very crowded, 1.7-6 cm long with axes 0.4-5.2 cm long and branches 0.7-2 mm wide, glabrous or puberulent in upper parts; peduncle 0.3-5 cm by 2.2 mm, glabrous; pedicels 1-1.5 mm long, glabrous or sparsely puberulent; subtending bracts persistent; bracts present on pedicel. Sepals ovate, 1.3-2.1 by 1.2-1.8 mm, 1.1-1.5 times as long as wide, apex rounded, ciliate, glabrous or sparsely puberulent outside, glabrous inside. Corolla completely white; tube 7-10.5 by 1.1-1.3 mm, 1.3-1.4 times as long as lobes, 3.3-6.5 times as long as calyx, pubescent in lower half of tube but not at base, throat glabrous, glabrous outside; lobes 5-10 by 1-1.5 mm, 3.7-6.7 times as long as wide, linear, apex acute, not ciliate, glabrous outside and inside. Stamens inserted c. 6.5 mm from corolla base which is c. 0.8 of corolla tube length in rehydrated flowers; anthers c. 1.4 by 0.4 mm, c. 3.5 times as long as wide, apex c. 0.3 mm from corolla throat, filaments 0.5 mm long, glabrous. Disk 0.7-1.1 mm long, 0.7-1 times as long as ovaries, glabrous, awl-shaped, apex acute. Ovaries 0.9-1.1 mm high, glabrous or very sparsely pubescent on top; style c. 5 mm long; style head c. 0.7 mm long. Fruit with a blunt hooked spur, 10-12 by 4-7.5 by 8-9 mm, spur c. 4 mm long, sparsely puberulent.
