A single entity in the genus Paspalum is known to be native to Iowa. With one exception, the Iowa specimens in the herbaria of Iowa State College and the University of Iowa are from the eastern half of the state. The material is from the following ten counties: Allamakee, Clayton, Clinton, Johnson, Muscatine, Louisa, Lee, Davis, Monroe and Harrison (Fig. 1). These collections have been made at varying intervals from 1875 to 1943. From the descriptive labels such as "a sandy river terrace," "Big Sand Mound, Muscatine Island," "sandy fields," the habitat is one of dry sandy situations. Future collecting may reveal a wider distribution for the state, as is suggested by the specimen from Harrison County and. the presence of the species in the surrounding states. Specimens from Nebraska, Missouri, Illinois and Wisconsin are in the Iowa State College herbariurn.
