Both of these native species are slightly spreading range grasses. Galleta grass occurs from Wyoming to California and West Texas while Tobosa is in West Texas and Arizona and south into Mexico. The bases of the stems of both are rhizome like. Stems may reach to 2 feet, with small, narrow leaves. Both are found under arid conditions and are highly drought resistant. They are moderately palatable while succulent, but not when dry.
