Discussion | Varieties 6 (6 in the flora). Crataegus pruinosa extends from Arkansas to Wisconsin, through the southern Great Lakes to southern New England, and, in the south, mainly in the Appalachians to northern Georgia. In the north of its range, Crataegus pruinosa is mainly a shrub of open successional habitats but in the south may commonly be a taller tree of open or thin woodlands. Many hawthorns have a little waxy bloom on their pomes; it is particularly prominent on Crataegus pruinosa and C. cognata compared to others. Some authors include in C. pruinosa their white-anthered counterparts, here assigned to C. cognata. Whereas C. pruinosa characteristically has entire or subentire sepal margins, some forms in the southwest of the range of the species (for example, C. calliantha Sargent, C. seducta Sargent) may have glandular-serrate sepal margins. They may represent introgression with C. coccinioides. The varieties of C. pruinosa are weakly differentiated from each other, most of them on leaf shape and size characters. The more widespread varieties constitute a range of morphotypes held together by common traits. Crataegus gaudens Sargent is a strikingly distinct form from Pennsylvania that has more or less elliptic leaves with lobes absent; it is clearly related to C. pruinosa. Note that 159. Crataegus ×coleae, a Michigan endemic, will key out here if its laterally scarred pyrenes are missed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Crataegus lacrimata is found abundantly over parts of the Florida panhandle and through adjacent Alabama and Georgia to South Carolina. Crataegus lacrimata is an upright, usually single-stemmed shrub with slender, more or less weeping branches and small, narrow, glabrous, bright green leaves. The plants are easily recognized among ser. Lacrimatae, the whole plant being almost completely glabrous, having narrow, nearly unlobed leaves, and being the only member of the series to possess more or less eglandular bracteoles. Only with poor material might the pubescent inflorescence of C. munda (dwarf, non-lacrimate) or C. crocea (tall, lacrimate) be confused. A form similar to C. lacrimata and with the same range, but apparently discontinuously larger, has longer leaves (blades 2.2–4 cm versus 1–1.7 cm) and larger flowers (petals 7–9 mm versus 5–7 mm) and more orange-colored ripe fruit.
