| Poa pratensis subsp. irrigata (Lindm.) H. Lindb. | |
| Publ. & Syn. | Poa subcaerulea Sm. in Sowerby, Engl. Bot. 14: t. 1004 (1802). Type: England: "Anglesea (on the mountains of Westmoreland and Cumberland)", leg. H. Davies. - Poa pratensis subsp. subcaerulea (Sm.) Hiitonen, Suom. Kasvio: 205, f. 5 (1933). |
| Notes | Subspecies irrigata is mainly a shore plant and native on and close to the seashores in the North Atlantic regions north to the Arctic in southern Greenland (or archaeophytic there), Iceland, and Norway. Sekretareva (1999) reported it as adventive for the Murman area. However, it is very common as native in coastal vegetation types in northeastern Norway east to the estuary of the border river Jakobselva between Norway and Russia. We therefore assume it to be native also in the Murman area but probably assigned under another name there. It occurs as adventive but established in arctic sites in northeastern Canada (at least Iqaluit in Baffin Island, Elven 1999, O) and as semi-established in Svalbard (Longyearbyen, Elven 2009-2010, O, TROM, abundant and flowering but perhaps not fruiting). The name P. humilis Ehrh. ex Hoffm. has priority at rank of species, based on a Swedish plant ("Upsaliae", leg. Ehrhart). The name subsp. irrigata probably has priority at rank of subspecies. Lindman's P. irrigata and Hoffmann's P. humilis seem to be based on the same type. |
