Discussion
A disjunct population of Carex geyeri is known from Centre County, Pennsylvania, well beyond the normal range of the species in the western mountains. The site should be re-examined to determine whether it persists there and whether it was native or introduced. Carex geyeri is an important native forage species in western montane grasslands (A. Cronquist et al. 1972+, vol. 6).
