54a. Crataegus coccinea Linnaeus var. coccinea

Scarlet hawthorn, aubépine écarlate

Crataegus acclivis Sargent; C. albicans Ashe; C. delecta Sargent; C. digna Sargent; C. ellwangeriana Sargent; C. lobulata Sargent; C. pedicellata Sargent; C. pedicellata var. albicans (Ashe) E. J. Palmer; C. pedicellata var. ellwangeriana (Sargent) Eggelston; C. pringlei Sargent var. lobulata (Sargent) Eggelston; C. uticaensis Sargent

Leaf blades ovate, 5–8 cm ˂widest in proximal 1/3˃ (length/width = 1.4–1.5), ˂elongate˃, plane, base broadly cuneate to truncate, rarely slightly cordate, lobe sinuses deep. Stamens (5–)8–10. Pomes usually suborbicular. 2n = 51, 68.

Flowering May; fruiting Sep–Oct. Brush, woodland margins, fencerows, overgrown pastures; 10–1300 m; Ont.; Conn., Ill., Ind., Maine, Md., Mass., Mich., N.H., N.Y., N.C., Ohio, Pa., R.I., Vt., Va., W.Va., Wis.; introduced in Europe.

Variety coccinea is found throughout the range of the species except for southern Quebec; it is the only variety found in the Appalachians south of Pennsylvania. An old report for Minnesota has not been confirmed. Crataegus albicans is a variant with particularly broad leaves and nearly glabrous inflorescences. Crataegus aulica Sargent perhaps belongs here. According to J. A. Macklin and J. B. Phipps (2002), much of the material named C. ellwangeriana Sargent [C. pedicellata var. ellwangeriana (Sargent) Eggleston] belongs to C. pennsylvanica Ashe.
