*CVU, *GipP, *Gold, *HNF, *HSF, *NIS, *Strz, *VRiv, *VVP. Also naturalised in Tas. Native to central and southern America. Apparently uncommon in Victoria but possibly overlooked due to its similarity to the very widespread Bromus catharticus. Most collections are from domestic gardens near Melbourne.

Synonymy follows Matthei (1986).
