摘要

Prairie cordgrass is a warm-season perennial grass. It is native to most of the prairies of most of the United States and Canada. It has an average height of 3 to 8 ft. The leaf blades, 3 to 13 mm wide and up to 30 inches long, are coarse, very tough,and thick. The margins of the leaf are serrated and sharp. Stems are stiff. It is strongly rhizomatous with very tough, scaly rhizomes. Seedheads are composed of 10 to 20 spikes attached to the main stem. Each spike has up to 40 spikelets, all-growing in two rows on the side of the spike away from the stem. The seeds are flat, paper-like with barbed awns that attach firmly to fur or fabric. There are approximately 183,000 seeds per pound. It is also known as ripgut, cordgrass, marsh grass, slough grass, fresh water cordgrass, and broadleaf.
