Shrub or treelet, (1-)2-6 m, practically glabrous; stem 4-8 cm Ø Branchlets slender, smooth, green, older parts covered with a thin greyish-brownish longitudinally fissured cork. Leaves ovate-or oblong-elliptic, sometimes ovate, apex subabruptly and for 1-2 cm obtusely subacumi-nate or apiculate, base ± rounded, slightly inequilateral, coriaceous, lucid green above, much paler beneath, 15-20(-30) by 8-12(-18) cm, midrib grooved only in the lower part above, strongly raised beneath, nerves 4-5(-6) pairs, the lower 2 (or 3) pairs usually closer together than the upper ones and found in about the lower third of the lamina, curved-ascending and +-looping, slightly raised above, more distinctly so beneath, reticulation of veins and veinlets dense and finely prominent on both faces; petiole 8-15(-20) by c. 3 mm. ♂ Flowers (B.S. 44073) glomerate on slightly supra-axillary swellings, tubercles or very short axes, sessile or almost so. Calyx lobes ovate, ciliate, c. 2 mm. Petals united to their lower ¾ into a tube, white, c. 5 mm. Filaments 3 mm; anther cells elliptic, 1.5 mm. Rudiment of ovary cylindric with a broadened base, glabrous as is the thick crenulate disk. ♀ Flowers solitary or few (rarely up to 8), details not known. Drupe ovoid, or rarely ellipsoid-subovoid, (2-)2.5-3 by (1.5-) 2-2.5 cm, round in Ø, green, with c. 5 prominent obtuse ridges from base to the subtruncate or very shortly apiculate apex, and may be with a few less distinct ones between; exocarp thin, predominantly spongious; endocarp hard, 1-1.5 mm, with c. 5 obtuse longitudinal crests.
Primary, rarely secondary lowland (Dip-terocarp) forest, up to 300 m, along river, apparently scattered.
