Habit | Shrubs, to 0.4 m. Stems prostrate or nearly so, carpeting, rooting; branches spiraled and distichous, dense, red to purple-black, slender, initially yellow-green strigose. | Shrubs, wide-spreading, 0.5–1.5 m. Stems weakly ascending, suberect, or decumbent; branches spiraled, purple-black, sometimes green and brown striate, initially strigose. |
Leaves | persistent; petiole 1–4 mm, strigose; blade obovate to broadly obovate, rarely suborbiculate, 5–14 × 3–9 mm, coriaceous, base obtuse or broadly cuneate, margins slightly revolute, veins 2 or 3, superficial, apex obtuse, sometimes emarginate, abaxial surfaces grayish, reticulate, initially densely strigose-villous, adaxial dark green, shiny, not glaucous, sometimes lightly rugose, glabrescent. |
persistent, petiole 1–5 mm, strigose; blade oblanceolate or oblong, rarely lanceolate, 8–17 × 3–8 mm, coriaceous, base cuneate, margins revolute, veins 2–4, superficial, apex rotund or obtuse, rarely emarginate or acute, abaxial surfaces grayish white, faintly reticulate, initially densely strigose or strigose-pilose, later glabrate, adaxial dark green, sometimes blue-green, shiny, not glaucous, not bulging between lateral veins, initially strigose, soon glabrate. |
Inflorescences | on fertile shoots 8–15 mm, usually with 4 leaves, 1(–3)-flowered. |
on fertile shoots 5–12 mm with 2 or 3 leaves, 1(or 2)-flowered, subsessile. |
Pedicels | 3–5 mm, strigose. |
erect, densely strigose. |
Flowers | 7–10 mm diam.; buds pinkish; hypanthium cupulate, strigose or pilose-strigose; sepals: margins villous, apex obtuse or acute, surfaces initially sparsely pilose-strigose; petals spreading, white, glabrous; stamens (15–)20, filaments white, anthers dark purple; styles 2(or 3). |
7–15 mm diam.; buds pink; hypanthium narrowly cupulate, densely strigose; sepals: margins densely villose-strigose, borders membranous, apex often red, acute or obtuse, sometimes shortly mucronate, surfaces often densely strigose-villous; petals spreading, white, glabrous; stamens 20, filaments white, anthers red-purple; styles 2[or 3]. |
Pomes | bright red to crimson, subglobose, 7–9 × 8–10 mm, slightly shiny, not glaucous, sparsely pilose; sepals suberect, sparsely strigose; navel slightly open; style remnants at apex on small projection. |
dark red with crimson, sometimes red, depressed-globose, 7–9 × 7–10 mm, dull or slightly shiny, glaucous, sparsely villous; sepals suberect or erect, villous; navel open; style remnants at apex. |

Discussion | Cotoneaster cochleatus was treated as a variety of C. microphyllus by L. Lingdi and A. R. Brach (2003); here the two are distinguished at species rank, following H. Nybom et al. (2005). Plants of C. microphyllus have a suberect habit, usually elliptic leaves (rarely broadly obovate) with acute apices, and pomes 6 mm wide; C. cochleatus is always prostrate and has usually obovate leaves (rarely suborbiculate) with blunt apices, and pomes 8–10 mm wide.

Cotoneaster integrifolius was treated as C. microphyllus Wallich ex Lindley var. thymifolius (Baker) Koehne by L. Lingdi and A. R. Brach (2003). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
