- Leaves: sheath smooth; ligule 1/4” tall, thin; blade 6” to 8” by 1/2”, prominent auricles at the base, smooth.
- Inflorescence: branching flower stalks, contracted lobes on short stalks; 4” to 6” long; more widely spread during blooming.
- Spikelets: 5/32” long; one floret per spikelet; flowering from late May to mid-June.
- Fruits: 1/8” long; with two tiny, hairy branches at the base of the mature floret; fruiting begins in mid-June; fruits begin dropping from the glumes in late June.
- Habitat: frequent in wet, open areas such as stream banks and waterways; sometimes in wet, open woods and occasionally on prairies.
