Discussion | 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 integra extends from Alabama to South Carolina and is concentrated in the northern half of peninsular Florida. The species is one of the more common members of ser. Lacrimatae in its main area of distribution. Crataegus integra is relatively variable in leaf shape and is notable for its almost entire leaf blades, the margins of which often have numerous, barely detectible teeth. This species often displays a considerable variety of leaf size even on one short shoot and has more venous leaves than many species of ser. Lacrimatae. One of the most different entities in the C. integra complex is C. sodalis (= C. dolosa). It has densely glandular petioles, denticulate leaf margins, short-shoot leaves broadly elliptic to broadly obovate, and rather large suborbiculate extension-shoot leaves, and perhaps should be considered part of C. alabamensis. It is concentrated in south-central Alabama. Crataegus integra differs from the C. illudens form of C. lassa in its proportionately narrower and usually shorter leaves, lacking the distinctive cuneate-cuspidate shape of C. lassa but also sometimes obscurely subterminally lobed. Crataegus integra is particularly common in the northern half of peninsular Florida, where C. lassa is rare. Crataegus constans Beadle, with less copious inflorescence tomentum, longer petioles, and proportionately larger and thinner leaves, is perhaps a shade form of C. integra.
