The culms are light green, terete and glabrous, although they are mostly covered by the sheaths. The sheaths are light green, finely ribbed, shiny or dull, and hairy. Leaves are soft and smooth, usually hairy near the base, 4-8 mm wide and with an open hairy sheath around the stem.

The central stalk of each raceme is light green, flattened, and about 1 mm. across. There are many pairs of one-flowered spikelets along the length of each raceme; they occur along only one side of the flattened stalk. Each ovoid spikelet is light green to brownish green, flattened, and about 3 mm. long. The lemmas enclose a single developing grain. The blooming period occurs from mid-summer to early fall. Each grain is ovoid and flattened like the lemmas. The root system is fibrous, sometimes the nodes of the lower culms will form new fibrous roots.
