Radicate, perennial herb. Stems 100-500 mm long, 1-2 mm thick, decumbent or ascending or stiffly erect. Mature leaves and bracts pale-green, alternate, sessile, variable, usually obovate-spathulate to oblanceolate on lower stem, grading to linear-lanceolate in upper stem, 8 × 2 to 30 × 10 mm; margins flat and distantly denticulate to strongly undulate, usually with scattered hairs on margins and lamina. Callus teeth 4-5 on each margin. Pedicels slender, 30-100 mm long. Flowers glabrous, 3-5-lobed, pastel lilac at anthesis, fading to off-white or pure white in different populations, 5-20 mm diameter, 4-9 mm long. Corolla rotate with shallow saucer-shaped tube, 1 × 3-4 mm; lobes spreading, 5 × 4 to 8 × 5 mm, broadly ovate, touching or overlapping in open flower. Style thickened at top, white. Calyx lobes glabrous, 1.5 × 1.0 to 3.0 × 1.5 mm, triangular; capsule glabrous 5-7 × 4 mm, ellipsoid to obconic, with protruding apical valves. Bud at anther dehiscence short and rounded. Self-fertile. Seeds 0.5 mm long.
