Crataegus brachyacantha occurs throughout Louisiana, where it is locally common, and in the adjacent parts of all surrounding states. A disjunct population was known in Georgia but it cannot be found there now. The species is seemingly more shade tolerant than many other hawthorns. Crataegus brachyacantha is among the taller hawthorns in North America; its petals turn orange with age or on drying. The short, recurved thorns and bitter, oblate-orbiculate, black fruit also are distinctive and help to distinguish C. brachyacantha from C. saligna of Colorado and Utah (ser. Cerrones), which is similar in foliage and flower. The names blueberry haw and pomette bleue may have a special appropriateness about late August when the waxy covering of the fruit is still thick and the underlying color is a dark purple. At maturity, the flesh is thin and bitter and the skin usually black. The fall foliage, brilliant lustrous orange, bronze, and red, suggests potential ornamental use. Forma leucocarpa Sargent is a white-fruited form, which was collected by E. J. Palmer at Natchitoches, Louisiana, September 1915; it is the only recorded white-fruited hawthorn.

Crataegus magniflora ranges through the southern Great Lakes area from Illinois and Wisconsin to Pennsylvania and Massachusetts. Two forms occur, one with a more nearly truncate leaf base, which is more common in Ontario, and a more fulleriana-like form, which is most common westward. The leaf of Crataegus magniflora is most similar to that of C. coccinea var. coccinea but differs in usually being a little larger, often relatively wider (length/width sometimes equal to 1.1), and in the base being more truncate to more or less cordate than is usual in var. coccinea. Crataegus magniflora was often identified as C. corusca Sargent before it was recognized that the latter represented a putative interserial hybrid of ser. Coccineae × ser. Molles origin.
