| Publ. & Syn. | Roshev., Bot. Mater. Gerb. Bot. Inst. Komarova Akad. Nauk SSSR 11: 29 (1949). Holotype (LE): Russian Far East: South Chukotka, the Anadyr valley near the mouth of Maina, 13. July 1933, leg. Vassiljev 1160. |
| Notes | Tzvelev (PAF proposal) recognized the arctic taxa assigned to sect. Secundae as four species. The main range is in North America and Greenland. Soreng et al. (2003) and Soreng (2007) treated them as two species, one with three subspecies. We follow that treatment. An additional species, Poa secunda J. Presl, occurs in bluffs with a prairie character north to Alaska and the Yukon Territory and may have been overlooked. Northwestern American material (ALA) of it is still mostly annotated as P. glauca. Records from the Arctic or the Borderline Arctic may be found when this material is revised. |
