Stems erect, ascending, or decumbent, often several from the base. Cauline leaves subsessile or lowermost attenuate to petiolelike base to 5 mm; leaf blade spatulate, obovate, or oblong-oblanceolate, (0.5-)0.8-2.5(-4) cm × (2-)4-10(-15) mm, gradually smaller upward, base attenuate, apex acute. Fruiting pedicels erect or ascending, (1-)1.3-1.8(-2) mm, subappressed to rachis, stout, straight, covered with stellate trichomes mixed with fewer, simple and forked ones. Sepals lanceolate, 2-3 × 0.8-1.3 mm, persistent till fruit maturity, pubescent as pedicels. Petals pale yellow, spatulate, 2.5-3.5(-3.8) × 0.6-1 mm, glabrous, often persistent, base attenuate, apex deeply emarginate. Filaments 2-2.5 mm, slender, neither appendaged nor toothed; anthers ovate, 0.3-0.4 mm. Ovules 2 per locule. Fruit orbicular or orbicular-elliptic, 2.4-3.5(-4) mm in diam., apex rounded or truncate; valves not veined, uniformly inflated except for a narrow flattened margins, with stellate trichomes mixed with longer, simple and forked ones; style (1-)1.5-2 mm, much broader at base, pilose and stellate at least along proximal half.
