Elymus canadensis B. S. Walters

Most often on sandy (or even somewhat marshy) shores and on sand dunes and in associated thickets; also in forests, especially along trails, river banks, and streams; occasionally with weedy tendencies along roadsides and disturbed areas.

The spikelets are often 3 at a node, especially toward the base of the spike, in this and E. wiegandii. Some specimens of E. riparius may resemble young E. canadensis superficially, but differ in narrower glumes with a more distinct terete portion at the hardened base, and in more numerous, less involute leaves. Elymus diversiglumis approaches Michigan in Wisconsin, and may be found in the western Upper Peninsula. It resembles a sparsely-flowered E. canadensis, and would usually key here, but differs in having very narrow glumes mostly less than 0.4 mm wide and veinless or with just one vein.
