Abstract

Grass Family (Poaceae). Bluebunch wheatgrass is a perennial native bunchgrass. Bluebunch wheatgrass is highly variable and grows to 1.5 to 4 feet (0.4 to 1.2 m) tall with seed spikes 3 to 8 inches (76 to 200 mm) long. The auricles are pointed and semi-clasping to nearly lacking. Leaves are lax, cauline, flat to in-rolled, 0.6 to 0.25 inches (4 to 6 mm) wide, and green to blue in color. The sheath is generally glabrous. Reproductive stems are erect, slender, and sometimes wiry with a wavy rachis. The lemma awns range from being short to prominent and divergent except on the beardless type where the awn is lacking (Hitchcock 1950).
