Crataegus biltmoreana is wide-ranging but somewhat scarce; it is known from Vermont to Georgia and west to Missouri and Arkansas, but is most abundant in Appalachia.
Crataegus biltmoreana is distinctive with its very hairy young twigs, leaves, and inflorescence branches, low stature, long thorns, large flowers, and yellow to orange pomes. Indumentum is the only consistent difference from C. intricata; specific rank is maintained because wide-ranging glabrous/hairy variants of one species are so unusual in North American Crataegus. Eventually, it may prove better to accept C. biltmoreana as a variety of that species. Rare forms with almost unlobed leaves, the sinuses shallow and lobes obtuse when present, may be the same.
