Taxonomic Comments
In 1994, Kartesz lumped Bromus luzonensis (= B. subvelutinus) material into Bromus marginatus (var. breviaristatus (Buckl.) Beetle); in 1999, Kartesz recognizes B. luzonensis and B. marginatus as separate species. In 1994, Kartesz recognized two varieties within his Bromus marginatus (B. marginatus var. breviaristatus (Buckl.) Beetle and B. marginatus var. marginatus), whereas in 1999, he does not recognize these varieties (although he still lumps B. marginatus var. breviaristatus (Buckl.) Beetle material into his B. marginatus). Finally, in 1994, Kartesz lumped Bromus marginatus var. seminudus material into Bromus polyanthus, whereas in 1999 Kartesz lumps B. marginatus var. seminudus into B. marginatus. Brainerd et al. (2016) include Bromus marginatus (= B. sitchensis var. marginatus) as a variety of B. sitchensis.
