Type: In colibus lapidosis Iberiae, circa Tiflis, M. Bieberstein (LE).
Distribution: Turkey, Turcomania, Transcaucasia, Afghanistan, Iran and Pakistan.
A highly polymorphic species specially in habit and pubescence of flower. A number of infraspecific taxa have been recognized by different authors (Ehrend., 1.c.). In Pakistan it seems to be a rare taxon and only one specimen from Kurram (Aitch. 517) has been seen, which is very near to subsp. capitata (Labill.) Ehrend.
