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.
