    Distribution: Central Asia (Tienshan, Pamir Alai), Mongolia, Pakistan, Kashmir and China (Xizang).

    The species is common in northern areas of Pakistan (Gilgit, Baltistan, Chitral) and Kashmir, on stony slopes generally near rivers and streams, between 2,500–3,500 m.

    A distinct species first described under Potentilla in 1808 and then transferred to another genus,Comarum L. by Bunge (1839) followed by Juzepczek (1941), and Schiman-Czeika (1969). This is not accepted by most other workers. Th. Wolf (1908) included it in Potentilla palustris (L.) Scop. = Comarum Palustre L. in the grex Palustres of his section Trichocarpae under the genus Potentilla. Potentilla salesoviana has carpels which are completely concealed whi le Potentilla palustris has completely glabrous carpels and the former is shrubby whi le the latter is a herb. It is appropriate to keep them apart in different subgenera within the genus Potentilla because of these basic contrasting characters.
