Abstract

An investigation was made of Elymus simplex to evaluate the current taxonomy and cytology. The study included herbarium specimens from Wyoming and Colorado and population samples from the type location in Wyoming. The most important taxonomic characters noted are: numbers of spikelets per node, lemma awn length, and habitat. The chromosome number of E. simplex is reported as 2n=28. E. simplex is a distinct species and should not be confused with E. salina, from which it differs morphologically.
