|discussion=<p>Plants of Liatris aspera from the Dakotas, Minnesota, Nebraska, Iowa, and Kansas have consistently sparsely to densely puberulent-hispidulous leaves (var. aspera); those to the east usually have glabrous leaves (var. intermedia); variation in vestiture occurs in Missouri, Illinois, and Indiana and identities in this large area would have to be arbitrary or typological if varieties were formally recognized. Variety salutans was recognized by Shinners on the basis of its deflexed (versus horizontal or ascending) heads; such plants occur in Texas, western Louisiana, and adjacent areas of Arkansas and Oklahoma.</p>
