| Publ. & Syn. | ?Empetrum purpureum Raf., New Fl. 3: 50 (1836). Described from Labrador (Canada). - Empetrum nigrum var. purpureum (Raf.) DC., Prodr. 16, 1: 26 (1869). - Empetrum nigrum f. purpureum (Raf.) Fernald, Rhodora 25: 83 (1923). |
| Notes | Mirré, Elven and Murray: Vassiljev (1961) reported Empetrum atropurpureum to possibly reach the Arctic in southern Alaska and northeastern Canada. Alaskan occurrence is improbable. The species is supported as an allotetraploid from E. nigrum and E. eamesii (Murray et al. 2009; Popp et al. in prep. a). We provisionally include E. purpureum as possibly synonymous with E. atropurpureum due to it being described from Labrador. Vassiljev reported E. purpureum from the Arctic in northeastern Canada north to Ellesmere Island and in Greenland. No other authors have accepted E. purpureum in recent times and especially not from Greenland or as far north as Ellesmere. We have not yet been able to confirm presence in the Arctic. |
