Notes on the Grasses of Southeastern Iowa

In 1933, Cratty (6) listed the grasses of Iowa, represented by specimens in the Iowa State College herbarium, in his paper THE IOWA FLORA. Twenty-eight years earlier, Pammell, Ball and Lamson-Scribner (23) published \u27\u27THE GRASSES OF IOWA, PART II,\u27 the only more or less complete treatment of Iowa grasses. Additional specimens of grasses have been collected in numerous localities since the appearance of these two papers; changes in the Rules of Botanical Nomenclature, together with detailed studies of certain genera, have made necessary some changes in the scientific names of Iowa grasses. For these two reasons, a recapitulation of present knowledge about Iowa grasses has seemed desirable
