First recognized as a distinct form in the central Mississippi Valley. The type site for Hardin Barbed is the Godar Site, Calhoun County, Illinois. Also called Hardin and Hardin Stemmed. The Hardin Barbed range is concentrated between Oklahoma and Indiana. In Wisconsin, it is rare north of the Wisconsin River.
Blades are lanceolate to triangular and are sometimes beveled or serrated from re-sharpening.
Stem is expanding with concave to straight bases. Stems sometimes show flaring ears. Hardin Barbed and Scottsbluff have several similarities but the major differences between them are the presence of barbs on Hardin specimens and the lack of serrations and beveling on Scottsbluff.
