Shrubs or trees, 70–80(–120) dm. Stems: twigs: new growth greenish, glabrous or slightly hairy; thorns on twigs straight to recurved, ± stout, 2–4 cm. Leaves: petiole length 30–40% blade, glabrate to densely hairy, glandular or eglandular; blade ovate or broadly elliptic to elliptic-ovate, (4–)5–8 cm, base broadly cuneate to subtruncate, rarely slightly cordate, lobe apex acute, margins serrate, sometimes doubly serrate, teeth 2 mm, adaxial surface usually densely scabrous young. Inflorescences: branches sparsely to densely pubescent. Flowers: hypanthium glabrous or densely pubescent; stamens (5–)8–10(–20), anthers pink to rose-purple. Pomes usually bright red, suborbicular to oblong, 10–14 mm, often sparsely pubescent (especially at ends); sepals spreading or missing.
Distribution
Ont., Que., Conn., Ill., Ind., Maine, Mass., Md., Mich., Minn., N.C., N.H., N.Y., Ohio, Pa., R.I., Va., Vt., W.Va., Wis., introduced in Europe.
Discussion
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.
Selected References
None.
