Shrubs, 1.5–2.5 m. Stems erect, arching, or spreading; branches spiraled or distichous, dense, greenish gray to maroon, not lenticellate, initially strigose. Leaves deciduous; petiole 4–8 mm, strigose; blade elliptic or ovate, sometimes obovate, 28–50 (–65) x 17–32 (–40) mm, chartaceous, base cuneate or rounded, margins flat, not revolute, veins 3–5, sunken, apex short-acuminate or acute, abaxial surfaces green, sparsely pilose-strigose, adaxial dark green, intensely shiny, not glaucous, flat or scarcely bulging between lateral-veins, slightly rugose, initially sparsely strigose; fall leaves intense dark red, yellow, or orange. Inflorescences on fertile shoots 25–50 mm with 4 or 5 leaves, 2–6 (–15) -flowered, lax. Pedicels 5–12 mm, sparsely pilose.

Discussion

Leaf glossiness is often retained on herbarium specimens and is visible with strong lighting and magnification.

Plants of Cotoneaster acutifolius of China and Mongolia are seldom seen in cultivation. Reports of it naturalized in North America are here referred to the commonly cultivated C. lucidus, which tolerates continental winters. No specimens have been seen to support reports of the latter from Montana and Oregon. Some reports of C. melanocarpus from Alberta and Manitoba (H. J. Scoggan 1978–1979, part 3) are here referred to C. lucidus.
