Habit | Shrubs, 0.5–1[–2.5] m. Stems weakly ascending or mound-forming [prostrate]; branches spiraled or distichous, dense, maroon, initially strigose. | Shrubs, 1–5 m. Stems erect, wide-spreading, arching, pendulous, slender; branches spiraled, purple-black, tomentose-villous. |
Leaves | persistent; petiole 1–3 mm, pilose-strigose; blade elliptic to narrowly elliptic, rarely lanceolate, 6–12(–20) x 2–6(–8) mm, subcoriaceous or coriaceous, base cuneate, margins revolute, veins 3–5, superficial, apex obtuse or acute, abaxial surfaces grayish green, reticulate, initially pilose-strigose, adaxial grayish green [rarely green], dull to slightly shiny, coating not recorded, slightly rugose, sparsely pilose or glabrous. |
persistent; petiole 4–7 mm, tomentose; blade elliptic, sometimes broadly elliptic, 15–35(–39) x 10–19(–26) mm, mid-coriaceous, base cuneate, margins flat, veins 4–6, usually superficial, sometimes slightly sunken, apex acute or obtuse, abaxial surfaces whitish tomentose, adaxial green to blue-green, dull, not glaucous, usually flat between lateral veins, initially sparsely pilose. |
Inflorescences | on fertile shoots 8–12 mm with 3 or 4 leaves, 1-flowered, 2–4-flowered on shoot tips. |
on fertile shoots 20–45 mm, usually with 4 leaves, (3–)5–15(–25)-flowered, compact. |
Pedicels | 1–3 mm, pilose-strigose. |
1–5 mm, tomentose. |
Flowers | 9–13 mm diam.; buds pink; hypanthium cupulate, pilose-strigose; sepals: margins villous, borders mostly reddish, membranous, apex acute or obtuse, surfaces pilose-strigose; petals spreading, white; stamens 17–21, filaments white, anthers purple-black; styles 2(or 3). |
[7–]8.5–10 mm diam.; buds white; hypanthium funnelform or cupulate, silky-tomentose; sepals: margins villous, borders white, narrow, membranous, apex red, cuspidate, sometimes acute or obtuse, surfaces tomentose; petals spreading, white, sometimes with hair tuft; stamens 16–20, filaments white, anthers dark pink-purple to purple; styles (1 or)2. |
Pomes | orange-red to red, depressed-globose, 8–10 × 9–11 mm, shiny, not glaucous, glabrous; sepals suberect, pilose; navel not recorded; style remnants at elongated apex. |
red, globose, depressed-globose, subglobose, or broadly obovoid, 5–9.2 × 5.5–9.5 mm, shiny, not glaucous, villous; sepals suberect, tomentose; navel open; style remnants at apex. |

Discussion | G. Klotz (1963) emended the diagnosis of Cotoneaster conspicuus to recognize erect plants as var. conspicuus and more decumbent plants as var. decorus. This variation in habit is not significant taxonomically and not unusual for an outcrossing diploid, so the emended description by Klotz of the species is superfluous.
