2n=
32 (4x). - Alaska. - Murray and Kelso (1997); probably also Johnson and Packer (1968, for O. nigrescens).
Elven and Yurtsev: The plant counted by Holmen (1962, Alaska, Howard Pass, 2n = 16, voucher combined with O. kokrinensis) should be identified.
Geography: Amphi-Beringian (E): RFE ALA CAN.
Notes: Yurtsev: On the Asian side, Oxytropis bryophila is known only from Koolen Lake in East Chukotka (1970, Yurtsev and Kozhevnikov).
Elven and Murray: The two tetraploids O. czukotica (mainly Asian) and O. bryophila (mainly American) are fairly similar and are major plants of the group in, respectively, East Chukotka and western Alaska, with some overlap. Intermediates have not been documented.
Oxytropis glaberrima is known from one locality in the northwestern Brooks Range in northern Alaska. We synonymize it with O. bryophila as a possible glabrous mutation. This possibility was also mentioned by Hultén (1968b).
