ABSTRACT
Study of diagnostic characters on herbarium specimens shows that approximately half of the Ohio specimens of the Stachys hispida-S. tenuifolia complex are easily assignable to one species or the other. The remainder, with various combinations of characters and/or intermediate characters, are referrable to a species only with difficulty or are impossible to place in either. Ohio specimens are best treated as a single variable species.
