| Oxytropis arctobia Bunge | |
| Publ. & Syn. | Bunge, Mém. Acad. Imp. Sci. Saint Pétersbourg 22, 1: 114 (1874). - Nomen novum for Oxytropis arctica var. uniflora Hook., Trans. Linn. Soc. London 14: 396 (1825). Type (GH, NY): Canada: Nunavut, "Barrow River, east coast Melville Peninsula, lat. 6721'N, on Parry's Second Voyage". - Oxytropis nigrescens var. uniflora (Hook.) Barneby, Proc. Calif. Acad. Sci., ser. 4, 27: 209 (1952). - Oxytropis nigrescens subsp. arctobia (Bunge) Hultén, Ark. Bot., n. s., 7, 1: 80 (1968). |
| Notes | Yurtsev: I consider Oxytropis arctobia to be clearly different from and outside the O. nigrescens aggregate. Elven and Murray: We agree with Yurtsev. Gillett et al. (2007, on the authority of Barneby 1952 and Welsh 2001) treated O. arctobia as a var. uniflora of O. nigrescens. We have seen nothing morphologically supporting a merger of O. arctobia with other species of the O. nigrescens group. The fairly large material we have seen of O. arctobia differs in several characters and with no transitions to other species. Welsh (2001) suggested a holotype for var. uniflora in LE, which seems improbable for a Hooker name based on a Canadian plant. |
