Cucurbita pepo Linnaeus var. ozarkana D. S. Decker, J. Ethnobiol. 13: 69. 1993

Variety ozarkana occurs in the central Mississippi valley and the Ozark Plateau. Populations in Alabama were included in var. ozarkana by C. W. Cowan and B. D. Smith (1993), but their evolutionary status was considered uncertain by D. S. Decker et al. (1993).
