Soft, fleshy, brittle-stemmed, glabrous, annual herbs. Stems up to 60 cm long, more or less decumbent, branched in the upper part. Cotyledons persistent, green, sessile, opposite, depressed-obovate, up to 15 cm broad and 7 cm deep. Leaves 4-12 cm long, 3.5-10 cm broad, ovate-cordate or subcircular, membranous, acute, cordate at the base, coarsely repand-dentate or subentire, petiolate, alternate or subopposite; stipules 2, minute, filiform. Raceme few-flowered. Sepals 4.5-5.5 mm long, 1-1.5 mm broad, narrowly oblong, membranous, very slightly cucullate; the inner two with a basal spur 1-2 mm long enclosing the large, ± tongue-shaped nectaries. Petals 9-10 mm long, 1.8-2.5 mm broad, narrowly obovate, rounded, clawed. Filaments 1.6-1.8 mm and 2.5-3 mm long, the 4 long ones ± widened at the base. Anthers 1-1.5 mm long.

Seeds 4-6 x 3-4 mm, ovoid but flattened at the broad (hilum) end, slightly ridged on one side; seed-coat of large cells mucilaginous, brown variously streaked with white or almost black; the flattened end paler or white, forming a ± circular-reniform strophiolar area round the hilum.
