Almost glabrous or glabrescent annual herb, 1.5-12 cm high; stem erect, branched divaricately, usually from or near the base, often terminating in the first umbel near the base and overtopped by the branches, with well developed hypocotyl, 5-20 mm long; cotyledons oblong, 4-8 mm long, usually present when fruits mature; leaf blade reniform, 3-13 mm long, 5-25 mm broad, 5- rarely 3-lobed, incisions about to the middle, basal sinus wide-angled to truncate, rarely acute, glabrous and dark-green above, glabrous or with a few scattered hairs and pale-green to glaucous below; lobes crenate with the centre-lobe usually with 3 blunt teeth towards the apex; petioles of lower leaves about twice as long as the blade, those of the upper leaves shorter; stipules conspicuous, membranous, white, ovate, more or less entire, adnate to the petiole for much of their length.

Peduncles leaf-opposed, much shorter than the petioles; umbels contracted to heads of c. 3-15 small flowers (c. 1 mm diam.); involucral bracts absent; petals greenish-white; fruiting pedicels to 1 mm long, thick.

Fruits c. 1.5 mm long, c. 2.5 mm broad, distinctly laterally compressed, reddish- to dark-brown when mature; carpophore very thin-subulate, c. 0.7 mm long, persistent; mericarps with prominent dorsal and intermediate and much less conspicuous lateral ribs, with c. 7 large blunt tubercles on either side of the dorsal rib and the outer side of the intermediate ribs, rarely also with some tubercles on the inner side of the intermediate ribs, usually leaving a smooth semicircular depressed area near the lateral ribs; styles thickened at the base, spreading outwards and then raising the stigmas slightly upwards, about half as long as the width of the mericarps.
