| Dryas punctata subsp. punctata | |
| Publ. & Syn. | Dryas octopetala var. viscida Hultén, Svensk Bot. Tidskr. 53: 528 (1959). See notes. |
| Notes | Elven and Murray: Yurtsev stated subsp. punctata to be very widely distributed from eastern Greenland across all of Eurasia and northwestern North America to northern Canada, almost everywhere sympatric with Dryas octopetala (and their assumed hybrid D. x vagans) or D. ajanensis. North American and northwestern European authors (except for Porsild) have not accepted this heterogeneity within their regions, and for the North Atlantic regions it is not supported by molecular evidence (Siegismund and Philipp 1999; Skrede 2004; Skrede et al. 2006). We suspect that the recognition of D. punctata from non-Russian areas is based exclusively on presence of some punctate glands, i.e., one character. We therefore restrict its range to the Urals, Siberia, and Chukotka. Hultén (1959b) obviously intended his var. viscida to cover both D. punctata Juz. and D. vagans Juz. (he cited both as synonyms) but he did not base his var. viscida on any specific previous name. He also neglected to indicate a type or any material and only mentioned that his variety occurs in "Siberia, North America, Greenland, Europe etc.", i.e., almost everywhere. The name is therefore without any meaning and illegitime in absence of any type information. Yurtsev: A canescent form was described as var. cinerea Jurtz., Fl. Arct. URSS 9, 1: 322, 273 (1984) [D. kamtschatica Juz. f. albicans (Kom.) Kom. ex Juz., Izv. Glavn. Bot. Sada SSSR 28: 323 (1929)] and reported from Chukotka and tentatively from Alaska. |
