A European relative of the Squirrel-tail-grass, the roughened awns of which are nearly as unpleasant to grazing animals as those of the native plant. Culms six inches to two feet tall, erect or decumbent at base, growing in tufts. Sheaths loose, shorter than the internodes on the long stems, overlapping on the shorter ones, the upper ones often inflated and enclosing the base of the spike; blades rough, two to six inches long. Spikes two to four inches in length, the spikelets in threes with lemmas awned, those of the central, fertile flower broader, with hairy margins, the awn nearly an inch long; the lateral ones shorter.

The weed should be suppressed by cutting so frequently as to prevent seed development.
