Achnatherum
''Achnatherum'' is a genus of flowering plants in the grass family, Poaceae. It includes 20 species of needlegrass native to temperate Eurasia and North Africa. Several needlegrass species have been switched between ''Achnatherum'' and genus ''Stipa''; taxonomy between the two closely related genera is still uncertain. In 2019 Peterson ''et al.'' reorganized the genera in tribe Stipeae based on molecular DNA studies, and placed the species from the Americas into other genera.Peterson PM, Romaschenko K, Soreng RJ, Valdés Reyna J (2019) A key to the North American genera of Stipeae (Poaceae, Pooideae) with descriptions and taxonomic names for species of ''Eriocoma, Neotrinia, Oloptum'', and five new genera: ''Barkworthia, × Eriosella, Pseudoeriocoma, Ptilagrostiella'', and ''Thorneochloa''.
