Scapes 1--3 cm, sparsely hirtellous, 1 or 2(--4)-flowered, or sometimes scapes obsolescent with a solitary flower arising from leaf rosette; bracts usually 2, oblong-lanceolate, conduplicate, sparsely hirtellous on proximal part, densely hirtellous on distal part, base slightly gibbous. Pedicel 1--2 mm. Calyx ca. 2.5--3 mm, parted scarcely to middle; lobes ovate-oblong, densely hirtellous, ciliate, apex obtuse to subrounded. Corolla white or pink; lobes broadly obovate, apex rounded to obscurely emarginate. Fl. Jun-Jul.
