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 cupressocollina is found through much of the Cypress Hills, where it may be common, and in a restricted area in the Bear's Paw Mountains, Montana. The species is distinctive in its tall, willowy, upright habit, leaf form, relatively long, slender thorns, and two to five year-old orange-brown bark. The flowers differ from those in ser. Douglasianae in their white anthers. The ripe fruit of C. cupressocollina is glabrous and plum red to purple-brown in late August, after which it ripens to a glossy purple-black. The large, pendulous clusters of fruit at once draw attention, as do the reddish tips of the sepals and the soft red-brown of the often nearly eglandular bracteoles when in flower. The colorful expanding bud scales are also rather striking. Crataegus cupressocollina is the first to flower of sympatric species.

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 |
