According to several authors, Bromus commutatus is not distinct from Bromus japonicus (Great Plains Flora Association 1986, Hickman 1993, Howard 1994, Welsh et al. 2003). There appears to be much taxonomic confusion in this group. Bromus commutatus may also intergrade with B. squarrosus (Howard 1994). In his 1999 Synthesis, Kartesz did consider Bromus commutatus distinct from Bromus japonicus; however, his treatment of this genus is being revised. Weakley (2005) also notes that the relative abundance, distribution, and habitat of B. commutatus and B. racemosus is poorly understood for Virginia, the Carolinas, and Georgia. It is very difficult to determine what information applies correctly to the species Bromus commutatus. In particular, the degree to which this species is able to spread into intact native plant communities, vs. being restricted to "weedy," disturbed places, is uncertain (NatureServe 2007).
