Cotoneaster cochleatus
Cotoneaster lacteus
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 lacteus sometimes is synonymized with C. coriaceus Franchet (for example, L. Lingdi and A. R. Brach 2003). As treated here, plants of this species are identified by their fertile shoots to 10 cm, scarcely shiny leaves to 120 × 60 mm with adaxial surfaces bulging between lateral veins, flowers to 150 in lax inflorescences, 6–9 mm diam. with cream petals, and larger, later-ripening fruits. Plants of C. coriaceus have fertile shoots to 5 cm, shiny leaves to 52 × 24 mm with flat adaxial surfaces, flowers to 50 in compact inflorescences, 9–10 mm diam. with white petals, and smaller, earlier-ripening fruits.
