Undershrubs, up to 1 m high, with an unpleasant smell; stems, petioles and pedicels velutinous to tomentose or densely pubescent with minute stellate hairs mixed with simple hairs. Leaves 0.5 - 6 x 0.4 - 5 cm, ovate to oblong or orbicular, shallowly cordate at base, obtuse or acute, occasionally rounded or truncate at apex, crenate-serrate, 5 - 7-nerved at base, densely velutinous with minute stellate hairs on both surfaces; occasionally with some patent simple hairs on lower surface particularly on veins; petioles 4 - 5 mm long; stipules 3 - 10 mm long, filiform, densely stellate-hairy mixed with some simple hairs. Flowers axillary, solitary or 2 - 5 in clusters particularly towards apices of branchlets; pedicels 2 - 10 mm long, accrescent up to 2 cm, jointed towards apex. Calyx 5 - 9 mm across, campanulate, somewhat accrescent; lobes triangular acute to acuminate, densely stellate-pubescent mixed with some simple hairs outside, sparsely stellate-hairy towards apex inside. Corolla yellow or whitish yellow, ca 15 mm across; petals obliquely obovate, truncate at apex; ciliate at base. Staminal column ca 2.5 mm long, simple hairy or glabrous. Ovary conical, stellate-hairy. Mericarps 8 - 10, ca 3.5 mm long excluding awns, radially ca 2 mm, both dorsal and ventral surfaces with prominent reticulations, and apical portion stellate-hairy, apex of mericarp with a pair of awns, 3 - 4.5 mm long, retrorsely hairy. Seeds ca 2 mm across, flattened reniform, glabrous except for a few short hairs near hilum, dark brown or black.
