Calamagrostis purpurascens R. Br.[FNA24, HC, HC2]
purple reedgrass

Publication: Bot. App. 731. 1823.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "The hairy adaxial leaf surfaces are a reliable diagnostic characteristic for C. purpurascens. Many specimens from Washington and Oregon currently identified as C. purpurascens belong to C. tacomensis. In addition to differing in its leaf vestiture, C. purpurascens has shorter awns and panicle branches, and more scabrous glumes, than C. tacomensis."
