High climbing shrub, much ramified. Branchlets slender, green-olivaceous when dry, striate, sub-glabrous. Leaves elliptic-, sometimes ovate-, rarely lanceolate-oblong, apex shortly acuminate, tip submucronate by the protruding midrib, base a little oblique, broadly cuneate to truncate-rounded, sometimes shallowly cordate, thin-chartaceous, entire, or rarely obsoletely repand to coarsely few-lobed, initially with scattered rather scabrid short hairs (also found on the inflorescence) underneath, early glabrescent, 9-15(-20) by 4-7.5(-10) cm, midrib and nerves slightly raised beneath only, lateral nerves 1-2 basal and 4-6 higher pairs, all curved-ascendent and rather obscurely inarching before the edge, no proper reticulation; petiole slender, 1.5-5(-7) cm. ♂ Umbels sub-globose, many-flowered, slenderly long-peduncled, axillary or slightly supra-axillary, rarely cauline, either solitary or 2-3 very laxly racemosely arranged on a rachis of 1-3 cm by c. 2 mm. Calyx shortly 4(-5)-lobed, very small. Petals 4(-5), united for 5-7 mm to a filiform tube below, free for the uppermost 2 mm, greenish yellow. Stamens 4(-5); filaments 1 mm; anther cells linear-oblong, base slightly divergent, 1.5 mm. Rudiment of ovary 4-gibbous, glabrous. ♀ Flowers arranged to many-and dense-flowered subglobose heads, these generally solitary from the axil on a slender peduncle 5-10 cm, rarely 2 or 3 laxly racemosely arranged along a short rachis, each head then very slenderly elongately peduncled. Calyx very small. Petals 4, not elongate into a tube below as in the ♂, oblong, thickish, 2 mm. Staminodes 4. Ovary subcylindric, densely hairy, crowned by the thick stigmatic pad. Drupe obliquely ellipsoid-ovoid, laterally compressed, (0.8-)l-1.2(-1.7) by 0.7-0.8(-1.2) by 0.6 cm, apex shortly and rather gradually attenuate, base suddenly narrowed to a kind of stipe 5-7 by 1 mm (bearing the persistent petals on its base); exocarp thin, laxly set with short strigose hairs, yellow to reddish; endocarp crustaceous, outside with numerous vertical low ridges and transverse connections, shallowly lacunose-reticulate in the dry fruit, inside with numerous low warts which leave their mark in the thus pitted seed.
Primary forest, sometimes along streams, generally in the lowland, rarely up to 700 m, in Buton I. on coralline limestone, apparently scattered or rare.
