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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Crataegus brittonii is a rare species with a scattered distribution. For a discussion of the possibly synonymous but untypified pink-anthered Crataegus rhodella Ashe and C. arenicola Ashe see J. B. Phipps and K. A. Dvorsky (2006).
