Indumentum simple hairs, either very short, whitish hairs (less than 0.5 mm long) and sometimes also long, yellowish, hirsute hairs (up to 1 mm long), see note. Outer bark light brown to greenish grey to grey, smooth (to fissured to scaly), c. 0.2 mm thick; under bark pale greenish cream to yellow to reddish to brown; inner bark pink to pinkish grey to dark red to brownish outside, coarsely fibrous to non-fibrous, soft, 3-6 mm thick; wood pale cream to straw to orange to orange-brown, firm, clean cutting, finely radially striate. Stipules triangular, 1.5-2 by 0.5-1 mm, outside subsericeous, inside glabrous, caducous. Leaves: petiole 3-8 mm long, channelled above, subglabrous to hirsute; blades (ovate to) elliptic, 7-32 by 3.3-12 cm, length/width ratio 2.1-3.6, papery to chartaceous, drying light green, base broadly attenuate, margin entire (to slightly crenate), apex usually damaged, acuminate, sometimes mucronulate, upper surface shiny (to dull) dark green above, glabrous to hairy on basal part of midrib, lower surface (sub)glabrous to softly hirsute, dull, pale to midgreen, venation slightly raised above, nerves 6-10 per side. Inflorescences cauliflorous and up to 30 together, or terminal and single, up to 75 cm long, damaged cauliflorous ones branching, side branches of racemes up to 100 cm long, subglabrous to hirsute, pistillate flowers single per node; bracts up to 0.5 by 0.5 mm, inside glabrous. Flowers 5-merous; calyx lobes 1.5-3 mm deep, glabrous inside, green, lobes shallow, 0.4-1 by 2-2.7 mm, apex rounded; petals ovate, 3.5-7 by 2-3.8 mm, concave, fleshy, c. 0.7 mm thick, apex acute, puberulous on both sides, white to cream to pale pink. Staminate flowers 5-15 mm diam., (faintly) scented; pedicel 5.7-20 mm long; stamens 10 (or 15), in a single whorl, connate to each other and adnate to pistillode, filaments very broad, strap-like, with thickened midrib, 1.5-2.3 mm high, hairy, white to pale pink, connective triangular, hairy, separating the thecae, anthers c. 0.7-0.8 by 0.6-0.7 mm, connective without appendix; pistillode 2.8-3.7 by 2.5-3 mm, puberulous, very pale green to light yellow. Pistillate flowers 3.7-4 mm diam., pedicel 3.7-10.5 mm long; ovary 2-4(-6)-locular, ovoid to obovoid, 2-3.2 by 1.8-2 mm, stigmas on top of ovary, 0.6-1 mm long, completely split, with a few papillae above and apical. Fruits laterally flattened to triangular to square to ± cylindrical in transverse section, broadest basally or apically, usually angular, 16-30 by 11-30 by 9-18 mm, subglabrous, whitish;wall very thick, 6-8 mm.
