Discussion

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.
