Leymus cinereus (Scribn. & Merr.) Á. Löve[FNA24, HC2]
Great Basin lyme grass

Publication: Bulletin of the Torrey Botanical Club 29(7): 467. 1902.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "Leymus cinereus grows along streams, gullies, and roadsides, and in gravelly to sandy areas in sagebrush and open woodlands. It is widespread and common in western North America. Leymus cinereus also resembles Psathyrostachys juncea, differing in its non-disarticulating rachises, larger spikelets with more florets, and longer ligules. Spontaneous hybridization between L. cinereus and L. triticoides is known; the hybrids do not have a scientific name. The rhizomes found in some specimens may reflect introgression from L. triticoides through such hybrids."
