This paper is the outcome of a careful study of the specimens of Labiatae in the herbarium of the State University of Iowa. The aim of this study is to provide a workable key to the genera and species, records of distribution, and up-to-date nomenclature for the Labiatae of Iowa. Fifty-nine species included in twenty-two genera are recorded for Iowa in the collection. Of the fifty-nine species studied fourteen are rare, ten infrequent, sixteen frequent and nineteen common. Detailed descriptions have been omitted except for the rare species and those which are not sufficiently described in the key for easy recognition. Forty-six of the recorded species are native while only thirteen are introduced. The source of each of the latter is noted in the text.
