| Carex glareosa Wahlenb. | |
| Publ. & Syn. | Carex marina auct. plur., non Dewey (1836). |
| Notes | The southwestern Alaskan subsp. pribylovensis does not reach the Arctic (see Excluded taxa). It is morphologically distinct. Egorova (1966a) mapped Carex glareosa as frequent along the northern coast of Siberia. Hultén and Fries (1986) mapped it from the Lena River estuary and surroundings. Malyschev (1990) reported it as very rare in Anabar-Olenyok, Kharaulakh, and Yana-Kolyma (i.e., the surroundings of the Lena and Kolyma estuaries). These discrepancies are probably due to the maps being based on the material in different herbaria. Two varieties have been proposed: var. glareosa and var. amphigena. The varieties have rather different perigynia (see Halliday and Chater 1969a; Toivonen 2002) but do not differ in other characters and are probably intergrading. The former is circumpolar; the latter is amphi-Atlantic in northwestern Europe (Iceland, Fennoscandia, northwestern Russia), Greenland, and northeastern Canada. They may merit rank as races but should be confirmed to differ in more than a single character before acceptance. |
