A brief discussion is presented on the ecologic, taxonomic, and economic features of the leguminous plants of the uplands occupying the northwestern half of Arkansas. The list of 37 genera and 115 species is compiled from the author's collection and from the specimens in the herbarium of the University of Arkansas collected in this part of the state. The geographic position of this area and its variety of ecological habitats indicate that it may yield nearly 175 species of legumes.
