Elymus multisetus (J.G. Sm.) Burtt Davy[FNA24, HC2]
big squirreltail

Publication: Univ. Calif. Publ. Bot. 1: 57.

Origin: Native

selected vouchers: WTU

Notes: The name Elymus multisetus (J.G. Sm.) M.E. Jones is invalidly published according to TROPICOS.

FNA24: "Elymus multisetus grows in dry, often rocky, open woods and thickets on slopes and plains, from central Washington and Idaho to southern California, Colorado, and northwestern Arizona, and from sea level to 2000 m. It has also been reported from Baja California, Mexico. It usually grows in less arid habitats than E. elymoides subsp. elymoides, but the two taxa are sometimes sympatric.

Wilson (1963) reported a wide belt of introgression between E. multisetus and E. elymoides subsp. elymoides from southeastern California to southern Nevada, but not in other areas where they are sympatric. There are also probable hybrids with Elymus glaucus and Pseudoroegneria spicata."
