Nomenclatural Changes For Some Grasses In California And The Muhlenbergia Clade (Poaceae), J. Travis Columbus, James P. Smith Jr.
Aliso: A Journal of Systematic and Floristic Botany
New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festuca, is here subsumed into Festuca, and the circumscription of Stipa is expanded to include all Stipeae (native and non-native) in California. In Stipeae, most currently recognized genera are not monophyletic. Attaining monophyly while bearing in mind identification for persons not expert …
