Epilobium laxum Royle. Type :— INDIA . Uttar Pradesh : Mussooree , Royle s.n. ( LIV ) ( Chen et al. 1992 ) . = Epilobium sadae Léveillé (1907: 588) . Type :— INDIA .

Clarke (1879: 587) . Lectotype (designated by Raven 1962a )— INDIA . Uttar Pradesh : Kumaun, 1832, Blinkworth in N. Wallich 6330 (K, isolectotypes BM, E, G). 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.
