Soviet Azerbaijan, N. & C. Iran. Ir.-Tur. element. Related to P. argentea and P. inclinata. Robust specimens collected from B8 Muş (between Varto and Köşker, 1600 m, Kotsaıy!) and B9 Bitlis (crater of Nemrut Da., 2400 m, McNeill 535!), which differ in their larger, obovate-oblong leaflets, and epicalyx segments shorter than sepals, are intermediate between this taxon and P. argentea.
