Chamaenerion Ség., Pl. Veron. 3: 168 (1754), nom. superfl. or nom. illeg. as not including present type species according to Holub 1972, but accepted as legitimate and validly published by Sennikov (2011) under ICN 11.3.

Note: Very often found as a synonym of Epilobium s.l. see Govaerts et al. (2023). As yet, there is no definitive evidence for favouring one taxonomic opinion over another.



The correct name for this genus has been solved satisfactorily according to most authorities. Chamaenerion Ség. (1754) does lack a generic description or diagnosis, however, the genus name was validly published by indirect reference to the generic description in Séguier (Pl. Veron. 1: 401. 1745), therefore, it has precedence (Sennikov, 2011). Incidentally, Chamaenerion Ség. (1754), when segregated from Epilobium L. (1753), is used by almost all authorities except for the Flora of China.
