On rock ledges; Distribution: From Afghanistan to Kashmir.

From Afghanistan, Baghlan, there is only one specimen, Podlech 11074 (M-Podlech!). C. koshwnikowii Litw. is a related, more robust species, which occurs from Pamir-Alaj to Tian-Shan Mts. Another related species is C. litwinowii Kük. from Tian Shan Mts. Their relation to C. chitralensis requires further study.
