Leaves petiolate (proximal) or subsessile (distal); blade elliptic, broadly lanceolate to ovate, 1-5 cm × 5-16 mm, base cuneate, margins entire, apex acute, glabrous, sparsely pubescent adaxially on midrib. Inflorescences terminal, 3-7-flowered, cymes dichotomously branched; bracts foliaceous, lanceolate, 5-30 mm, soft, margins entire, distal ones ciliate on margins and adaxial vein. Pedicels erect, 5-45 mm, softly pubescent. Flowers 10-16 mm diam.; sepals 5, obscurely veined, narrowly triangular, (5-)7-10(-12) mm, margins narrow, membranous, apex acuminate, glabrous or with shortly ciliate margins; petals 5, equaling to slightly shorter than sepals; stamens 10; styles 3, ascending, ca. 2.5 mm. Capsules straw colored to pale brown, broadly ovoid, ca. 5 mm, shorter than sepals, apex obtuse, opening by 3 valves; carpophore absent. Seeds brown, broadly reniform, ca. 2 mm diam., coarsely sulcate-papillate. 2n = 60.
