Annual or perhaps sometimes perennial. Stems decumbent or ascendent, usually soft and spongy, (5-)12-20(-38) cm tall, indistinctly 4-sided, rooting only at lowest nodes. Leaves lanceolate to narrowly ovate, 9-35(-50) mm long, 3-11(-18) mm wide, with sunken glandular dots, base tapering, margins distinctly toothed particularly towards the tip, tips subacute. Bracteoles 2, linear, 1-1.5 mm long. Flowers pedicellate, solitary in leaf axils; pedicels 4-5(-9) mm long, shorter than the subtending leaves. Sepal lobes divided to the base, overlapping, with conspicuous net-like nerves (at least in fruit), glabrous, unequal; the outer 2 larger, broadly ovate, at anthesis 6-7 mm long increasing to ± 6 mm in fruit, 2-4 mm wide; the inner 2 and the median one 3-4 mm long. Petals 4-6 mm long, white usually with purple veins or pink to violet; petal lobes weakly 2-lipped; the upper lip entire or slightly notched, ± 2.5 mm long, ± 1.2 mm I wide, glabrous; lower lip equally 3-lobed, the lobes oblong to spatulate. Stamens in 2 subequal pairs; filaments subequal, 2.5-2.8; anther locules ± 0.5 mm long. Capsules ellipsoid-ovoid to oblong-spherical, 3-4(-5) mm long, ± 2.5 mm in diameter, 2-or 4-valved. Seeds prismatic, 0.6-1 mm long, the surface net-like.

It is a tropical plant.
