Herb, sometimes suffrutex, perennial, the stem usually erect, up to 1.2 m high, puberulus with short viscid hairs and sparsely hirsute with longer simple hairs on the younger parts. Leaves with the petiole slender, usually 1.5-3.5 cm long, viscid-puberulus and hirsute, the stipules subulate, 1-2.5 mm long, persistent; blade ovate, cordate at the base, long-acuminate at the apex, irregularly serrate at the margin, up to 7.5 cm long and 3.5 cm broad, much reduced toward the apex of the stem and branchlets, thin, 5-or 7(-9-11)-palminerved, the main veins prominulous above and beneath, stellate-puberulus on both surfaces but the indumentum denser below. Fl'owers solitary in the axils, often with another flower or an accessory flowering branchlet arising later from the same axils, ultimately forming altogether a leafy paniculiform inflorescence, the pedicel short to usually elongate, filiform, articulated generally above the middle, 1-2.5 cm long, viscid-puberulus and sparsely hirsute; calyx campanulate, subplicate-5-angulate, 5-6.5 mm long, membranous, green, 10-ribbed, viscid-puberulus and/or hirsute along the veins and margins, moderately accrescent, the lobes deltoid, conspicuously acuminate, 3-3.5 mm long; petals obovate-obtriangular or broadly so, inconspicuously oblique, unguiculate, slightly emarginate at the apex, 5-6.5 mm long and 3-5 mm broad, yellow, buff or white; androecium 3.5-4.5 mm long, the staminal tube ca 2-3 mm long, sparsely whitish-hirtellous; styles ca 3.5-4 mm long, connate basally. Mericarps 5, trigonous, ca 3 mm long (awns included), thin-walled, puberulus toward the apex, apically 2-aristate, the awns 0.5-1.2 mm long and puberulus with antrorse or spreading hairs, the dorsum convex, nearly smooth as the lateral walls, dehiscent apically; seeds trigonous, ca 1.5 mm long, glabrous except for a few scattered minute hairs around the hilum.
