Perennial grass
A perennial grass that has both rhizomes and stolons and is capable of forming a turf or mat of fine leaves. Leaves are rolled in the bud, without auricles, and have a ligule that is a fringe of hairs about 1/2 mm long. Leaf blades are 2 to 7 inches long by 2 to 5 mm wide and smooth to only sparsely hairy above but usually only with a few hairs near the leaf base. Leaves emerge from opposite sides of the stem and have margins that are slightly rough. Leaf sheaths are usually distinctly flattened. Seedhead consists of three to seven fingerlike spikes that originate from a single point. Individual spikes are 1 to 3 inches long and flattened.
