Shrubs or small trees, 1–7 m. Stems 1–20, ± colonial. Leaves fully unfolded or nearly so; petiole (8–)11.3–18.1(–25) mm; blade elliptic-oblong to suborbiculate or obovate, (27–)38–59(–78) × (19–)26–43(–55) mm, base rounded to subcordate, each margin with (0–)4–11(–16) teeth on proximal 1/2 and (0–)3–6(–8) teeth in distalmost cm, largest teeth more than 1 mm, apex rounded and mucronate to subacute, abaxial surface densely (sparsely) hairy by flowering, surfaces sparsely (moderately) hairy (or glabrous) later. Inflorescences (4–)7–10(–13)-flowered, (20–)30–51(–68) mm. Pedicels: 0–2 subtended by a leaf, proximalmost (8–)11–23(–36) mm. Flowers: sepals recurved or spreading after flowering, (1.8–)2.5–4.1(–6) mm; petals linear to narrowly spatulate, (8–)10.7–16.1(–20) × (2–)3.5–5.6(–7) mm; stamens (16–)19–21(–24); styles (4 or)5, (1.6–)2.5–3.4(–4.6) mm; ovary apex densely (moderately) hairy. Pomes dark purple or almost black, 10 mm diam. 2n = 2x, 3x, 4x.
Phenology: Flowering May–Jun; fruiting Jul–Aug.
Habitat: Margins of woods, river ledges, shorelines, rocky slopes, crevices of open rock faces and cliffs, noncalcareous to slightly calcareous sites
Elevation: 0–1000 m

Discussion
This treatment follows G. N. Jones’s (1946) and E. G. Voss’s (1972–1996, vol. 2) with the inclusion of Amelanchier huronensis in A. sanguinea. The former was considered to differ from A. sanguinea in having longer proximalmost pedicels, sepals, and petals, but overlap occurs in the ranges of these characters. Moreover, A. sanguinea has been seen far from the range of A. huronensis (southern Ontario, Michigan, Minnesota, and Wisconsin) with petals as long as the longest reported for A. huronensis. Occurrences of A. sanguinea in Kentucky and North Dakota are questionable, as no specimens were actually seen to confirm the presence of this species from these states.
Amelanchier sanguinea has shorter petals than A. amabilis. Amelanchier humilis differs from A. amabilis and A. sanguinea in having shorter proximalmost pedicels, erect inflorescences, and shorter petals. Amelanchier amabilis, A. sanguinea, and, to a lesser extent, A. humilis resemble western North American congeners.
Amelanchier sanguinea flowers 10 to 14 days after A. arborea and A. laevis, according to K. M. Wiegand (1912), and at the same time as A. amabilis. Hybrids between A. sanguinea and A. bartramiana, A. canadensis, A. laevis, and A. spicata have been reported (M. L. Fernald 1950; P. Landry 1975). The authors have observed A. sanguinea flowering with A. amabilis but no putative hybrids were observed.
