| Carex rostrata Stokes | |
| Publ. & Syn. | Carex utriculata sensu V.I. Krecz. (1935), non Boott (1839). |
| Notes | Porsild (1932) and some earlier authors have suggested Carex rostrata to have been introduced to southern Greenland from northern Europe in Medieval times, because it only occurs within the region of Norse farming settlements. This hypothesis must be rejected because subfossils of C. rostrata well predating the Norse immigration have been found in southern Greenland (see Pedersen 1972). The Greenland sites taken into use by the Viking farmers were naturally the climatically most favourable places they could find and therefore also those with most occurrences of native, relatively thermophilous plants. This consideration is relevant for several other species suspected by some authors as Norse adventives in Greenland (e.g., Carex lyngbyei and Leymus arenarius). |
