Notes: This agamospermous plant has mostly been named as Calamagrostis purpurea in comparatively recent northwestern European literature (e.g., Hylander 1953b; Clarke 1980b; Elven 1994), by Hämet-Ahti et al. (1998) as C. purpurea subsp. phragmitoides, and by Elven et al. (2005) as C. phragmitoides. We now accept it as a species apart from the presumably sexual and mainly Siberian C. purpurea (see below) because it differs morphologically, in ploidy level, and reproductively. There are morphological indications that the sexual tetraploid C. canescens or a progenitor of that species is one of the parents of C. phragmitoides. The other parent might be sexual tetraploid C. epigeios or a progenitor, or (less likely) C. purpurea s. str.
