Varieties 4 (4 in the flora). Crataegus scabrida is variable in leaf shape and size, as well as in pubescence of adaxial leaf surfaces and pedicels. The species falls into four reasonably well-marked varieties, only the first two of which are frequent. The range of the species as a whole is somewhat poorly documented because of frequent incorrect identification. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Crataegus communis is uncommon and often wrongly annotated as C. straminea. The species has broadly elliptic leaves with small, very obscure or lacking, subobtuse lobes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
