Discussion

Varieties 2 (2 in the flora).

Crataegus berberifolia is widespread from Texas to Missouri, Florida, and Virginia; it is particularly abundant in Louisiana.

Crataegus berberifolia is little differentiated from some forms of C. crus-galli, except in indumentum; it has relatively small and less variably shaped leaves. Its distribution is quite different. Intermediates with hairy leaves and glabrous inflorescences or nearly glabrous leaves and hairy inflorescences may represent hybrids with C. crus-galli (where they might be reached in the key). Such a situation is found in C. araioclada. Abrasion of the adaxial leaf pubescence may occur, rendering identification more difficult with fruiting material. Crataegus berberifolia has a plethora of yellow and orange-fruited forms, particularly from southern Louisiana. Crataegus fera and C. tersa are red-fruited, C. crocina yellow. The fruit color in the type is unknown; E. J. Palmer (in specimen annotation) called it yellow-orange. A form with exceptionally white-tomentose leaves near Copenhagen, Louisiana, is probably this species. Crataegus regalis var. paradoxa (Sargent) E. J. Palmer, from Missouri and adjacent Kansas and Arkansas, is probably a hybrid between the deeply serrated 'regalis' leaf form of C. crus-galli and a form of C. berberifolia. Two common forms of C. berberifolia occur, treated here as varieties: var. engelmannii with ten pink anthers and var. berberifolia with 20 cream anthers. Forms with 20 pink or ten cream anthers also occur sporadically.

Crataegus gattingeri extends from Missouri to Pennsylvania south to Louisiana, Alabama, and Georgia; it should be sought in southern Illinois and Indiana.

Crataegus gattingeri is similar to the variably hairy C. pruinosa var. virella, which has normal-sized anthers. Considerable similarity occurs between C. compacta and C. gattingeri; both may have stipitate-glandular bracteoles, the leaves and flowers are about the same size, and the thorn and twig colors are similar. In the latter species a greater range of leaf shape occurs, from narrowly ovate to practically deltate, and bases rounded to broadly cuneate. The lobes and apices of the leaves of C. gattingeri are usually much sharper. Crataegus gattingeri is also superficially similar to small-leaved forms of ser. Tenuifoliae such as C. iracunda, which also usually has particularly small leaves at anthesis. It differs from the latter primarily in its 20 stamens, small anthers, much less hairy adaxial leaf surfaces at anthesis, and more glandular-bracteolate inflorescences. These two may be difficult to differentiate in fruit. The author has not come across C. gattingeri var. rigida E. J. Palmer, from Indiana and Kentucky, which apparently differs from the widespread type variety in its stouter and flexuous twigs, stouter thorns, and smaller flowers. It would not seem to be part of C. gattingeri. Crataegus arcana Beadle represents a somewhat similar form of possible conspecificity.
