Very common grass throughout its range where it can be found in wet, open sites, usually in abundance where regular disturbance occurs. It is the largest Dichanthelium in the region and is recognized by its wide leaves and stem; large, stiff hairs on the sheath with pustular bases that are nearly sharp to the touch; and habitat.
Most similar to D. latifolium whose leaf sheaths are glabrous save for marginal cilia.
Spikelets: 2.4-3.6 mm long, 1.2-1.5 mm wide, narrowly ellipsoid, sparsely pubescent.
