DistributionCentral and southern Mountains only, though as this is a Northern species, it certainly could be found in the northern NC mountain counties. A specimen from Transylvania County (herbarium NCU) is actually E. riparius.

N.S. to Yukon, south to NC, TX, AZ.
AbundanceRare to very uncommon. This is a Watch List species.
HabitatRiverside scour zones and banks, montane hardwood-pine slopes, often where quite rich.
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 CommentsOnly the nominate variety occurs in NC.

Ryegrasses 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. Identification of some species requires a dissecting scope or at least a 10x handlens.
