Description
Achnatherum aridum is a resident of high desert scrub and woodland habitat at some elevation. It is a tuft-forming perennial bunchgrass without rhizomes. The bunches of stems reach a maximum height of around 85 centimetres (33 in). The inflorescence is a panicle often partly enfolded in the narrow sheath of the uppermost leaf. The spikelets have hairlike awns 4–8 centimetres (1.6–3.1 in) long.[1]
