2n=
18 (2x). - Alaska, Canada (NW, W). - At least five reports.
Geography: North American (N): ALA CAN?
Notes: Elven and Murray: Yurtsev (PAF proposal) did not accept Dryas drummondii as reaching the Arctic but Hultén (1968a) mapped it into the Arctic in Alaska in the Brooks Range and Romanzoff Mountains, perhaps also in the Arctic in the Yukon Territory.
In AFLP markers, D. drummondii was distinct from all other investigated Dryas. Even if a phylogeny cannot be reconstructed from AFLP markers, this suggests that D. drummondii is 'sister' to all other Dryas.
