Discussion
Festuca calligera is a poorly known, often overlooked species. It grows in grasslands and open montane forests, at 2500-3400 m, from southern Utah to south-central Wyoming and central Colorado, south to Arizona and New Mexico. It is often found with F arizonica. Festuca calligera has frequently been included in F. ovina (p. 422).
