Notes: FNA24: "Calamagrostis rubescens is similar to C. koelerioides. The two have traditionally been distinguished by the presence of hairs on the leaf collars of C. rubescens, and their absence from C. koelerioides; a more reliable differentiation is the shorter lemmas, glumes, and awns of C. rubescens."
