Taxonomic Comments

This record is for Hesperocyparis arizonica in the narrow sense, excluding Hesperocyparis glabra (syn. Cupressus arizonica ssp. glabra, Cupressus glabra), Hesperocyparis nevadensis (syn. Cupressus arizonica ssp. nevadensis, Cupressus nevadensis), and Hesperocyparis stephensonii (syn. Cupressus arizonica ssp. stephensonii, Cupressus stephensonii) (Adams et al. 2009). Little (2006) transferred all Western Hemisphere Cupressus to the genus Callitropsis and Adams et al. (2009) further isolated the Western Hemisphere cypress lineage into a new genus Hesperocyparis. Little (2006) and Adams et al. (2009) considered the following distinct from Hesperocyparis arizonica: Hesperocyparis glabra (syn. Callitropsis glabra, Cupressus arizonica ssp. glabra, Cupressus glabra), Hesperocyparis nevadensis (syn. Callitropsis nevadensis, Cupressus arizonica ssp. nevadensis, Cupressus nevadensis), and Hesperocyparis stephensonii (syn. Callitropsis stephensonii, Cupressus arizonica ssp. stephensonii, Cupressus stephensonii), which Flora of North America (1993, vol. 2) include in synonymy.
