Discussion

Reports of Cotoneaster franchetii from Colorado (J. Ells 2006) are here referred to C. lucidus. A few specimens escaped in Washington have red filaments, not pink, but otherwise agree with C. franchetii. Other escapes in Washington suggest the closely related C. wardii W. W. Smith, distinguished by semievergreen habit, longer fertile shoots, more lax and elongate inflorescences, and white anthers. The entire complex needs biosystematic review.

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.
