DistributionThroughout the state, including the Outer Banks.

N.S. to B.C., south to FL and CA; Eurasia.
AbundanceFrequent to common. Where found, plants may be abundant.
HabitatVarious wetlands, including freshwater marshes, interdune marshes, river banks and shores, swamp forests and openings, clearcuts, roadside ditches.
PhenologyFlowering and fruiting July-October.
IdentificationThe plants generally are 2-3 feet tall, with a terminal inflorescence. The spikelets are pale green, overlapping, half-moon shaped, flattened, and bristly on the margins, giving them a resemblance to cultivated rice. All cutgrasses have scabrous leaf margins, this one particularly so; thus, it is not a good idea to wade through a stand of it in shorts. This cutgrass has the lower branches of the inflorescence whorled or nearly so; in the others the lower branches are alternate or rarely opposite.
