Subalpine Fir (Abies lasiocarpa (Hook.) Nutt.)

Also classified as Abies bifolia A.Murray bis.

Some authorities split this species into three separate taxa, the "coast range subalpine fir" which is alternatively called either just Abies lasiocarpa or Abies lasiocarpa var. lasiocarpa, the "rocky mountain subalpine fir", either called Abies bifolia or Abies lasiocarpa var. bifolia, and the "corkbark fir", either Abies arizonica, Abies lasiocarpa var. arizonica, or Abies bifolia var. arizonica. Some authorities recognize one or more of these as subspecies rather than varieties. We follow POWO's scheme which does not recognize the first two taxon as separate, not even as varieties, and recognizes the third as a variety but not a proper species. Because at least four different classification schemes are widely in use, it is of key importance to check which scheme a particular source uses before concluding what populations they are referring to. The same name may refer to different groupings of populations.
