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.) |
Crataegus ×vailiae, with its similarities to C. uniflora, may be a hybrid between that species and a member of ser. Macracanthae, most likely C. calpodendron. Fruit color is recorded as in cultivation at Kew; B. F. Bush (on herbarium label) noted it as deep red and succulent on wild plants in Missouri. Crataegus conjungens appears to be a smaller form of C. ×vailiae. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
