Flowers exannulate, mauve with a white eye and lobes emarginate. Locally abundant at 4000-4600m, growing on steep slopes and cliff faces and is more compact in exposed situations. It may be confused with P. atrodentata (which does not have basal bud scales). Compare also with P. sharmae from Nepal.
