- R. Br., Chlor. Melvill.: 6 (1823). Described from Melville Island the Winter Harbour area, 1819-1820, probably in the Northwest Territories (Canada). Type probably in BM. - Ranunculus pygmaeus subsp. sabinei (R. Br.) Hultén, Ark. Bot., n. s., 7, 1: 58 (1968).
- Ranunculus sabinei var. majusculus Tolm., Fl. Arct. URSS 6: 211 (1971). Described from "insula Ayon" in West Chukotka (the Russian Far East). No specimens mentioned.
2n=
32 (4x). - Far East (N), Canada. - Mosquin and Hayley (1966, see below); Zhukova and Tikhonova (1971).
Not included: Whittemore (1997) reported the chromosome number to be octoploid (2n = 64). This is probably based on Fedorov (1969) who erroneously included the counts of Mosquin and Hayley (1966, see above) from Melville Island as 2n = 64.
Geography: Asian (N) - amphi-Beringian - North American (N): SIB RFE ALA CAN GRL.
Notes: Ranunculus sabinei occurs within the range of R. pygmaeus, sometimes in company with it, but then well distinguished morphologically, chromosomally, and partly also ecologically. Hultén (1968b) was reluctant to accept it but was countered by Tolmachev (1971b): "The conviction of authors who based their opinions on study of adequate material of R. sabinii thus contradicts the doubts of those who did not study this species directly obviously referring to Hultén". We agree with Tolmachev after having seen R. sabinei together with R. pygmaeus in several localities. These two are independent species and perhaps not very closely related.
Elven and Murray: Presence in Alaska is confirmed from six populations (ALA) within an area of ca. 20 x 10 km at Barrow, the northernmost point of Alaska.
