Distribution: —N Pakistan, Jammu & Kashmir, U Ganga & Indus.

Note: — Epilobium laxum is distinctive by virtue of its large flowers and distributed in western Pan-Himalaya (Chen et al. 1992). Chen et al. (1992) mentioned that the “ holotype ” of E. laxum should be deposited in LIV, but they did not see this type. In this study, we do not determine the type status of E. laxum . Similarly, although both Raven (1962a) and Chen et al. (1992) noted that the “ holotype ” of E. sadae (Duthie 1046) is deposited in G, we are not sure its type status. According to Art. 9.1, we leave the type status issue open for further perusal.
