Abies lasiocarpa var. arizonica

Corkbark fir is an extremely southern variant of the subalpine fir (A. lasiocarpa), in fact it was earlier held to be a separate species. It is most easily distinguished by pale grey, almost cream-coloured, soft, corky bark. The needles are dense and a beautiful blue-grey, like those of the southern mountain forms of the subalpine fir.
