This is recorded by R. R. Stewart (l.c.) from the Kurram valley, based on Aitchison 545. The locality Ali Khel, however, is on the Afghan side of the frontier in the Kurram valley.

The record must be considered doubtful as no other localities outside of the Caucasus, Soviet Central Asia and China are known for Calamintha debilis.
