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.
