Hordeum vulgare spikelets (6-rowed) B. S. Walters spikelets (6-rowed)

Railroads, roadsides, and fields, escaped from cultivation and not long persisting. First collected in 1905 in Wayne Co.

In some plants (2-rowed barley) the lateral spikelets of each group of 3 are sterile; in others (6-rowed barley) the lateral spikelets are well developed and fertile. Both forms are found in disturbed ground in Michigan. The narrowly lanceolate glumes of this species are nearly always silky.
