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.
