- ?Gentianella detonsa subsp. yukonensis J.M. Gillett, Ann. Missouri Bot. Gard. 44: 215 (1957). Holotype (DAO): Alaska: Richardson Hwy, 4 miles south of Delta Junction, 28. June 1951, leg. Cody and Webster 5587. - ?Gentianopsis detonsa subsp. yukonensis (J.M. Gillett) J.M. Gillett, Canad. J. Bot. 57: 186 (1979).
2n=
(1) ca. 50 (ca. 4x). - Siberia (the Lake Baikal area). - Zuev (1997).
(2) ca. 70. - Siberia (S). - Krogulevich (1976b, 1978).
(3) 78 (6x). - Russia (E), Siberia (N), Far East (N). - Zhukova et al. (1977); Zhukova and Petrovsky (1977); Löve and Löve (1986a).
The report of 2n = ca. 50 may represent a tetraploid at 2n = 52, and the reports of 2n = ca. 70 may represent hexaploids at 2n = 78. The reports referred above and below support x = 13 as the base number of Gentianopsis.
Not included: Reports of 2n = 26 and 52 from China (for G. barbata) might belong to related species.
Geography: Asian (N/C) (& amphi-Beringian?): SIB RFE.
Notes: Elven & Murray: We are in doubt where to assign the American Beringian subsp. yukonensis. It does not belong within our more restricted concept of G. detonsa, perhaps rather within G. barbata. It occurs in interior Alaska and the Yukon Territory but does not reach the Arctic. It has not yet been recombined as a race of G. barbata.
