Caespitose perennial, with many sterile shoots at the base. Flowering stems 10-30 cm tall, erect, usually simple, slender, 2-4-noded, retrorsely puberulous below, puberulous and viscid above. Basal leaves linear-oblanceolate to spathulate, 14-32 × 1.5-4.5 mm, apex acute, base attenuate into short petiole, both surfaces puberulous, margin ciliate at the base, 1-veined or venation obscure. Cauline leaves similar, but gradually smaller than basal leaves, linear-oblong to linear-lanceolate, few and remote, sessile, sometimes with sterile axillary branches. Inflorescence usually strict compound dichasia to subcapitate, 3-15-flowered, puberulous and viscid. Bracts linear-lanceolate, sparsely to densely puberulous, margin membranaceus and ciliate especially at the base. Peduncles 2-23 mm long, puberulous and viscid. Bracteoles similar, but lanceolate-ovate and gradually smaller than bracts. Pedicels up to 2 mm, puberulous. Calyx 10-nerved, 6-9 mm long, cylindrical-campanulate to campanulate-clavate, whitish-purple, sparsely to densely puberulous; teeth broadly ovate to triangular, ca. 2 × 2 mm, obtuse to ± acute, with broadly membranaceous and densely ciliate margin. Anthophore 2.4-3.1 mm long, glabrous. Petal purplish-pink, 10-12 mm long; limb broadly obovate, 3.5-4.5 mm long, distinctly divided to ca. 2/5; lobes broadly oblong, ca. 2 × 2 mm; claw elliptic-oblong, slightly exserted beyond calyx, 6-7 × 1.5-1.8 mm, pilose, not auricled; coronal scales 2, oblong, 0.5-0.7 mm long, rounded at tip. Stamens and styles slightly exserted from the calyx; filaments usually glabrous or sometimes sparsely pilose. Styles 3.5-7 mm long. Capsules narrowly ovate, 5-7 × 2.5-3.5 mm, exserted from the calyx. Seeds brownish, usually orbicular-reniform or rarely oblong, 1.1-1.6 mm long, flattened, rugulose. Fl. & Fr. 6-7, rocky slopes on calcareous steppe, 1700-1750 m.
