Comments

This is a very variable species in which some workers (Markgraf l.c.) have reognised a number of subspecies, others (Pobedimova in Fl. U.R.S.S. vol. 18.1952) have treated some of these as species. I have accepted this taxon in a broader sense.

‘Duthie 15766’ from’ Waziristan, Kaniguram, 6500 ft’ looks different and needs further study.
