Panicles 3.5-9 cm long, 6-10 mm wide. Glumes 4-6 mm, connate in the lower 1/4, membranous, sides pubescent, keels not winged, finely ciliate, apices acute, parallel or convergent; lemmas 4-6 mm, connate in the lower 1/3, glabrous or the keels sometimes ciliate apically, apices acute, awns 5-10.5 mm, geniculate, exceeding the lemmas by (1)2.2-5.5 mm; anthers 2-4 mm, yellowish, orange, reddish, or purplish, varying within a population. Caryopses about 1-1.2 mm. 2n = 28, 42.
Alopecurus pratensis is native from temperate northern Eurasia south to North Africa. It is now widely naturalized in temperate regions throughout the world. It grows in poorly to somewhat drained soils in meadows, riverbanks, lakesides, ditches, roadsides and fence rows. It has been widely introduced as a pasture grass; it may also have become established from ballast or imported hay. The earliest collections are from coastal New England; it is now known from most provinces and states.

From Flora of Indiana (1940) by Charles C. Deam
Specimens of this species have been collected in Tippecanoe County, and I have it from Wells County, where it was well established when collected in 1932.
