Type:— CHINA. Tibet, Lhozhag County, Lhakan, 3150 m, crevices, August 2013, Y. S. Chen et al. 13–1387 (holotype PE).

Herbs perennial. Roots attenuated, ca. 3 mm across. Stems many from one caudex, caespitose, 10–18 cm tall, branched at upper part, puberulent. Leaves alternate, sessile, up to 5 mm long, 2.5 mm wide, both surfaces densely puberulent, base cuneate, apex rounded or acute, margin entire or with 1–2 pairs of teeth. Flowers solitary, terminal on main stem or both on main stem and branches. Calyx tube entirely adnate to hypanthium, obdeltoid, densely puberulent, 10-ribbed, but the five entering calyx lobes stronger than the others, broad-triangular, 3.5 mm long, 2 mm wide, apex acute, entire, densely puberulent. Corolla pale blue, tubular-campanulate, 1.4 cm long, lobed to near middle, puberulent outside; corolla lobes 6.5 mm long, lanceolate. Stamens 6 mm long, glabrous. Style 1.6 cm long, exserted; stigma trifid.

Notes:—This new species resembles Campanula cana Wallich (1824: 101) , from which it differs distinctly in having its leaves much smaller and sessile, flowers solitary, calyx lobes entire, and plants entirely covered with one type of hairs: being densely puberulent.
