A descriptive study of the woody plants from Mingo Wilderness Area in the Southeastern Missouri Lowlands contiguous with the Ozark Highlands was conducted from June 1977, through June 1979. Seven forest community types are described within the regional Southern Floodplain Forest and Oak-Hickory Forest. Geographical floristic affinities, relative abundance values, and vegetational community types are presented in an annotated catalogue comprising 128 trees, shrubs, and vines.
