Earlier taxonomic studies in the genus Spartina of the Gramineae show the existence of but one of the sixteen species in Iowa, Spartina pectinata Link. That it is widely distributed throughout the state is evident from Figure 1. The counties identified by dots have yielded specimens presently accessioned into the herbaria of Iowa State College, State University of Iowa and Simpson College. In addition, the species has been observed in numerous other counties although records are not authenticated by specimens entered into institutional herbaria.
