Type: Type: Peru, Dombey (P).
Distribution: Distribution: Pakistan (Punjab & N.W.F.P.; introduced); a South American species widely introduced as a winter forage species under the name “Rescue Grass”, and now found as an escape in most temperate countries.
Comment/Acknowledgements: Bromus catharticus (Bromus unioloides) and Bromus willdenowii are segregates from an imperfectly known South American complex. The temptation to call Asian material anything other than Bromus catharticus should be resisted until the complex as a whole is more fully understood.
