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.) |
L. Lingdi and A. R. Brach (2003) confused Cotoneaster tengyuehensis with C. glomerulatus W. W. Smith, a species with small fruits 5 mm in diameter, with 5 pyrenes and styles, and slightly smaller leaves to 40–50 mm. In the flora area, C. tengyuehensis is more likely to be mistaken for C. franchetii, which is a true evergreen with orange-red, obovate to obconic fruits, and pink to purple stamens. Naturalized shrubs of C. tengyuehensis drop their foliage in midwinter. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
