| Poa glauca Vahl | |
| Publ. & Syn. | ?Poa anadyrica Roshev., Bot. Mater. Gerb. Bot. Inst. Komarova Akad. Nauk SSSR 11: 26 (1949). Type (LE): Russian Far East: South Chukotka, the Anadyr area, Mount Talizhak, 29. July 1932, leg. L. Tyulina 200. |
| Notes | Poa glauca is fairly uniform in the more northern arctic zones but becomes extremely polymorphic in the forest belts and in the boreal mountain ranges, especially in the broadly amphi-Beringian regions. Much of this polymorphy may be due to several taxa being merged inside the current concept of P. glauca, some of it to hybridization, and this latter part may be difficult to classify satisfactorily. Three Russian Far East species proposed in Tzvelev's draft (P. pekulnejensis, P. filiculmis, P. magadanensis) may either be different taxa or may belong to such hybrid swarms. See notes to the aggregate and to P. nemoralis. |
