Varieties 3 (3 in the flora). Crataegus coccinea is found from extreme southeastern Minnesota, Wisconsin, and Illinois through the southern Great Lakes area to coastal Maine, and in the Appalachians at higher altitudes to North Carolina; it is common in the north of its range. Crataegus coccinea varies in leaf shape and planeness and in fruit shape. In some areas, more or less pure populations of the different variants occur. It is easiest to group the variation around two relatively strongly marked varieties with ten or fewer stamens, vars. coccinea and pringlei, between which intermediates are common, and the 20-stamen var. fulleriana.

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.

1. Leaf blades (elongate), ovate (length/width = 1.4–1.5), 5–8 cm (widest in proximal 1/3), plane, lobe sinuses deep, bases broadly cuneate to truncate, rarely slightly cordate; pomes usually suborbicular. | var. coccinea |
1. Leaf blades broadly elliptic to elliptic-ovate (length/width = 1.2), 4–7 cm, plane or concavo-convex, lobe sinuses often shallow, bases rounded to broadly cuneate; pomes usually oblong or suborbicular | → 2 |
2. Stamens 8–10; leaf blades conspicuously concavo-convex; pomes usually oblong. | var. pringlei |
2. Stamens 20; leaf blades usually plane, rarely concavo-convex; pomes usually suborbicular. | var. fulleriana |
