The correct name for this genus has been solved satisfactorily according to most authorities. In the meantime Chamerion is used here for now although probably illegitimately. 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.
