Magnolia fraseri , a tree of the Appalachian mountains and upper piedmont, and its close congener M. pyramidata , of the lower piedmont and coastal plain, are sometimes confused taxonomically, but they differ in a series of good characters. Some investigators have treated them as geographic varieties or subspecies of M. fraseri . Magnolia fraseri differs from M. pyramidata in being a much larger tree with wide-speading branches, different leaf shape, larger flowers, more numerous stamens, and larger follicetums. In their present geographic distribution, these taxa are allopatric. In some localities M. fraseri may be abundant, as in the area near Sugar Grove, Smythe County, Virginia, where hundreds of specimens occur. It is a desirable flowering tree, occasionally cultivated.

The largest known tree of Magnolia fraseri , 32.6m in height with a trunk diameter of 94 cm, is recorded from Great Smoky Mountains National Park, Tennessee (American Forestry Association 1994).
