Elymus virginicus L. var. jejunus (Ramaley) Bush

This taxon is usually distinct but often intergrades with var. virginicus; Ladd & Thomas (2015) still favor species status. Weakley et al. (2017; W) have favored species status for this and other varieties of virginicus, but deeper analysis is desirable. Var. jejunus is largely midwestern, generally occurring in thin woods and thickets on uplands and along stream terraces. It is also widely scattered or adventive into northeastern states (FNA 24). Most Ky. records may be from adventive situations. The only Appalachian coll. is from a low meadow near a railroad in LAUR (KY), and it could be considered just a waif dispersed from afar.
