Notes: FNA24: "Elymus scribneri grows in rocky areas in open subalpine and alpine regions, at 2500–3200 m, often in windswept locations, in southwestern Alberta and the western United States. It is often confused with E. elymoides, but differs from that species in having only one spikelet per node, wider glumes, and more tardily disarticulating rachises. It also resembles E. sierrae, from which it differs in its disarticulating rachises, denser spikes, and shorter anthers.

Several taxonomists have suggested that Elymus scribneri consists of fertile hybrids between E. violaceus and E. elymoides. This suggestion is supported by the frequency with which the three taxa are sympatric, the morphological variation exhibited by E. scribneri, and cytogenetic data (Dewey 1967)."
