Description: Perennial, tufted grass, 50-150 cm tall, from thick, ascending rhizomes forming large clumps; stems erect, stout, usually finely but copiously hairy or sometimes smooth above. Leaves flat to in-rolled, 6-15 mm wide; ear-shaped lobes usually developed at some leaf-bases; ligules more or less fringed with fine hairs, scarcely 1 mm long. Inflorescence a stout spike, (10) 15-30 cm long, 1-2 cm wide; spikelets paired, 4- to 6-flowered. Glumes and lemmas usually very soft-hairy, scarcely awned.
Ecology: Moist to mesic sandy or gravelly beaches and shoreline forests in the lowland zone.
Notes: This used to be a dominant grass on dunes until the introduction of European beachgrass. First Nations used dunegrass for weaving packstraps, basket handles, and tumplines.
