Stems procumbent to weakly ascending, diffuse, generally glabrous or with one or two rows of hairs.. Leaves all distinctly petiolate; blades ovate to broadly ovate, acute, shortly apiculate, more or less cordate at the base, varying considerably in size, from 3 mm. long and 3 mm. broad to 18 mm. long and 14 mm. broad, midrib and main veins fairly conspicuous, the latter anastomosing near the margin, glabrous or with a few scattered hairs; petioles 0.3–1.7 cm. long, pilose near the base and with scattered hairs or glabrous in the upper part.. Flowers solitary and axillary to the upper leaves; pedicels 5–18 mm. long, with some scattered hairs or glabrous.. Sepals 4, narrowly lanceolate, acute or shortly acuminate, 3–4 mm. long, pilose on abaxial surface, margins scarious.. Petals absent (at least usually) or vestigial.. Styles 2.. Capsule shorter than the calyx.. Seeds 1–4 per capsule, papillate.. Fig. 11.
