Comments: ― Bromus catharticus was not reported from Guatemala by Swallen & McClure (1955) or from Panama by D'Arcy (1987). Plants in México are referable to B. catharticus var. catharticus, one of three varieties currently recognized in the species. Bromus catharticus var. rupestris (Spegazzini 1896: 76) Planchuelo & P.M. Peterson in Peterson & Planchuelo (1998: 54) is known from central and southwest Argentina, and B. catharticus var. elatus (E. Desv. in Gay 1854: 438) Planchuelo (2006: 556) is native to South America and introduced in California and New Zealand (Planchuelo 2006). In México the species is used as fodder (Saulés & Dávila Aranda 1992).
