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 magnificus was synonymized with C. multiflorus Bunge by L. Lingdi and A. R. Brach (2003). Flowers of the latter are 9–10 mm wide in clusters of 10–20, the flowering pedicels are to 7 mm, and the leaves are smaller, thinner, and tend to be ovate. Plants of C. magnificus have flowers 12–14 mm wide in clusters of 5–12, flowering pedicels are to 12 mm, and the leaves are larger, thicker, and mostly elliptic. Reports of wild C. multiflorus from Illinois (F. Swink and G. S. Wilhelm 1994; J. T. Kartesz and C. A. Meacham 2003) and Iowa (W. R. Norris et al. 2001; Kartesz and Meacham) are referred to C. magnificus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
