Discussion

Reports of Cotoneaster mucronatus Franchet escaped in Oregon (P. F. Zika and E. R. Alverson 2005) are here referred to C. fangianus.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

The difficulties of typification and taxonomy for black-fruited species were discussed by J. Fryer and B. Hylmö (1997). Some collections of Cotoneaster villosulus from eastern Washington need study. They approach the very similar C. hsingshangensis J. Fryer & B. Hylmö, a Chinese species with larger, more wrinkled leaves, more globose pomes, and less densely hairy flowers.
