We have two varieties represented in Wisconsin: var. longifolia and var. magna Scribn. & Merr. The former is native to the northwestern part of the state and adventive elsewhere. It occurs in sand barrens, oak barrens, dry prairies, and along roadsides and railroads. The Great Lakes endemic var. magna is mostly restricted to Lake Michigan dunes but has also been found along sandy roadsides and in dry prairies. The two varieties differ in their panicle shape: open in var. magna and narrowly contracted in var. longifolia. If included in Sporobolus, this would be called S. rigidus (Buckley) P.M. Peterson and var. magna would be called var. magnus (Scribn. & Merr.) P.M. Peterson.
