AbundanceSee the full species account. For some odd reason, the NCNHP has placed this taxon on a Watch List (W3) for questionable taxonomy.
HabitatRiverside scour zones and banks, montane hardwood-pine slopes.
PhenologyFlowering and fruiting July-September.
IdentificationAt 3-4.5 feet tall, this wild-rye is more robust than most of our other species. Its inflorescence usually arches or nods (as does E. riparius), and the awns curve outwards (not curved in E. riparius).
Taxonomic CommentsRyegrasses or Wild-ryes (genus Elymus) are noted by their evenly spaced leaves and elongate, terminal inflorescence that recall cultivated rye or wheat. Each floret produces several long, skinny awns (shortest in E. virginicus sensu stricto). Identification of some species requires a dissecting scope or at least a 10x handlens.
