During 1951 and 1952 a study of 116 species of aquatic monocotyledons was made, primarily from specimens in the herbaria of Iowa State College and the State University of Iowa. The selection of aquatic species was based, for the most part, upon those listed by Muenscher (1944) and from data on herbarium specimens as well as from limited personal field experience. Of the 14 families included, the Gramineae, with 17 species distributed in 11 genera, and the Cyperaceae, with 34 species in 7 genera are the best represented. Potamogeton, with 18 species is the largest of the 42 genera studied, Eleocharis and Scirpus, both of the Cyperaceae, being second and third in size, with 12 and 11 species respectively.
