This taxonomic study is concerned with all the species of Aster known by the writer to occur in Iowa. It is an endeavor, first, to provide a useful key to the species of this genus known to be found in Iowa, second, to present an up-to-date nomenclature of the species, and third, to show the distribution of the species of Aster in Iowa as recorded in the collections studied. Deam's "Flora of Indiana" has been used for the sequence of species, and the key has been largely adapted from his. Research work by recent botanists has shown that some of the specific names are invalid by rules of nomenclature and by the change of taxonomic concepts. Such names are listed as synonyms in the treatment of the species.
