Abies lasiocarpa var. arizonica, first described by Clinton Hart Merriam (1855-1942); work completed by John Gill Lemmon (1832-1908), is commonly known as Arizona Cork-bark fir. It differs from the type in the following ways:
Description. Has thickened, 'corky' bark that is white to grey and deeply furrowed, and has very glaucous foliage. In other respects it is like var. bifolia.
Distribution. Var. arizonica occurs in United States - Arizona, Colorado and New Mexico, typically at elevations of 7,700 to 11,000 feet (2,400 - 3,400 m) over sea level, where it is commonly seen growing with Picea engelmannii.
