About Achnatherum calamagrostis (L.) P.Beauv.
The scientific name of this species is Achnatherum calamagrostis (L.) P.Beauv. The species was first described by Linnaeus in 1759 under the name Agrostis calamagrostis, in his work Systema naturae per regna tria naturae. In 1812, Palisot de Beauvois transferred the species to the genus Achnatherum, publishing this reclassification in his Essai d'une Nouvelle Agrostographie. The translated original protologue for Agrostis calamagrostis reads as follows: 74. Agrostis. Calyx two-valved; one-flowered; corolla somewhat smaller; stigmas longitudinally hispid. *Awned. Calamagrostis. Panicle thickened; outer petal (lemma) wholly woolly, awned at the apex; culm branched. (Scheuchzer, Gramina, p. 146.)
