Mostly high alpine species with a dormancy of 4-6 months when they are usually snow covered (or dry). Pubescent leaves (except for P. jigmediana), usually efarinose (except sometimes P. wollastonii), few flowers either solitary, capitate or spicate, sessile, reflexed or nodding, corolla bell shaped with the lobes more or less in line with the tube (except P. jigmediana, P. sherriffiae, P. ludlowii), white or purple, with capsule rounded and included in the calyx. Close to Section Muscarioides. It is uncertain whether P. ludlowii is distinct from P. sherriffiae and whether P. siphonantha is distinct from P. cawdoriana.
