First collected on the Surkia La, near the Kang La on the Nepal-Sikkim border. This is a very small species, no more than 3cm tall with spathulate leaves, incised-dentate in the upper margin, and scabrid on both surfaces. The flowers are blue-purple with a white eye, exannulate, a few hairs in the throat and emarginate lobes. Not initially described to have stolons, but field observations in Nepal show this character. Compare with related species P. waddellii and P. muscoides.
