Herbs perennial, pubescent throughout. Stems caespitose, diffuse, slender, arising from a thick irregular rootstock, leafless at very base (probably underground), but forming a leaf rosette and branched at ground level. Leaves subcordate to broadly ovate, proximal ones long petiolate (to 4 cm), petioles of distal leaves gradually shorter; cauline leaves broadly ovate or suborbicular, (0.5--)1.5--2(--3.5) × (0.5--)1--2(--2.5) cm, both surfaces villous, glabrescent, margin ciliate, apex acute or mucronulate. Dichasial cymes lax, rachis, pedicels, and calyx densely pubescent; bracts ovate, small, herbaceous. Pedicel 0.7--2 cm. Calyx campanulate, 4--5 mm, 10-veined; calyx teeth ovate-obtuse, 1.5--2 mm, densely villous. Petals oblanceolate, 7--9 mm, claws slightly exserted beyond calyx; limbs white or pale pink, 4(or 6)-lobed, lobes oblong; coronal scales small, scarious. Androgynophore 0.5--1 mm. Stamens 10, included; filaments inflated at base, glabrous. Styles 3. Capsule ovoid, ca. 2.5 mm, shorter than calyx. Seeds violet-brown, orbicular to reniform, ca. 0.7 mm in diam., minutely tuberculate. Fl. Jun--Jul, fr. Aug--Sep.
