Lectotype (first step designated by Raven 1962a: 351, second step designated here):— INDIA. Sikkim: India orient, in montibus Sikkim ad Lama Koryr , 3480–4267 m, 1849, Hooker s.n. ( K000913980 !, isolectotype K000913981 !) .

Distribution: —C Nepal, U Yarlung Zangbo, L Yarlung Zangbo, S Hengduan, Yarlung Zangbo-Brahmaputra.

Note: —There may have been hybridization events happened between this species and Chamaenerion angustifolium or C. speciosum ( Decaisne 1844: 57) Hoch & Gandhi (2020: 60) , since morphologically intermediate populations were found in overlap areas of those species ( Chen et al. 2007).

The protologue of E. conspersum only provided the habitat, altitude, and collector name of the type ( Haussknecht 1879). Raven (1962) considered that the “ holotype ” was deposited in K. However, the type material is a gathering with duplicate specimens in K (K000913980 and K000913981), which have the same collecting information. This situation can be considered as inadvertent lectotypification under Art. 7.11 and 9.10 of the ICN ( Turland et al. 2018). A second step is here lectotypified between the two speciemens in K (Art. 9.17 of ICN, Turland et al. 2018). The specimen K000913980 matches better with the protologue of E. conspersum and is designated as the lectotype here.
