摘要
本文为即将修订的《杰普森手册》验证了加州十个草(禾本科)分类群的新组合和名称。此外，在最近的分子系统发育研究的指导下，本文将10种非加利福尼亚草转移到Muhlenbergia (Chloridoideae: Cynodonteae)，以实现属的单系化。从系统发育角度来看，Lolium一直被认为嵌套在Festuca中，在这里被纳入了Festuca，而Stipa的范围扩大到包括加州所有的Stipeae(本地和非本地)。在Stipeae中，大多数目前公认的属不是单系的。扩大针茅属范围的指导原则是在考虑非针茅属专家身份的同时实现单性。新发现的有:加州elymoides变种，hordeoides变种elymoides, Festuca perennis, Hilaria亚群。Pleuraphis, Muhlenbergia brevigluma,M。安德拉,M。天空,M。野蔷薇,M。香,M。phleoides, M。plumiseta, M。spatha, M. tricholepis, M. uniseta, S. barbatus vara arabicus, Stipa chaetophora, S. divaricata, S. exigua, S. mauritanica和S. purpurata。
Nomenclatural changes for some grasses in California and the Muhlenbergia Clade (Poaceae).
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 nonnative) in California. In Stipeae, most currently recognized genera are not monophyletic. Attaining monophyly while bearing in mind identification for persons not expert in Stipeae were the guiding principles in expanding the circumscription of Stipa. Newly recognized are: Elymus elymoides var. californicus, E. elymoides var. hordeoides, Festuca perennis, Hilaria subgen. Pleuraphis, Muhlenbergia brevigluma,M. diandra,M. imperfecta,M. multiflora,M. paniculata,M. phleoides,M. plumiseta,M. spatha, M. tricholepis, M. uniseta, Schismus barbatus var. arabicus, Stipa chaetophora, S. divaricata, S. exigua, S. mauritanica, and S. purpurata.
