Taxonomic Comments

Zika et al. (2015) describe Luzula cascadensis as a new species. Per Zika et al. (2015),"this taxon has been treated as L. campestris var. columbiana. The epithet columbiana could be raised to the species level. We have chosen not to do so because "cascadensis" better describes the plant's range and habitat and because L. campestris var. columbiana was used very little (Kirschner et al. 2002, St. John 1936), so its disappearance should not cause much confusion." Kartesz (1994, 1999) do not mention L. campestris var. columbiana. FNA (vol. 22, 2000) includes L. campestris var. columbiana in the synonymy of L. comosa.
