| Cassiope tetragona (L.) D. Don | |
| Publ. & Syn. | D. Don, Edinburgh New Philos. J. 17: 158 (1834). - Andromeda tetragona L., Sp. Pl.: 393 (1753). Lectotype (LAPP): Sweden: "Lapland". Linnaean Lapland Herbarium 166, left hand specimen (Stone and Stone in Cafferty and Jarvis 2002b: 752). |
| Notes | The closely related Cordilleran subsp. saximontana (Small) A.E. Porsild reaches north to the non-arctic parts of Alaska and the Yukon Territory. A study based on AFLP markers (Eidesen et al. 2007) suggested that subsp. saximontana is 'sister' to the circumpolar subsp. tetragona. The study also suggested some interesting phylogeographic patterns concerning the Asian or Beringian origin of this circumpolar plant. |
