Discussion
Aristida purpurea var. fendleriana grows on open slopes, hills, and sandy flats, at low to medium elevations, from the western United States into northern Mexico. It is often confused with var. longiseta, having short basal leaves and short panicles, but plants of var. fendleriana have narrower lemma apices and thinner, shorter awns than those of var. longiseta.
Selected References
None.
