Hesperocyparis glabra, known as the Arizona smooth bark cypress or smooth Arizona cypress, is a conifer native to the American Southwest, with a range stretching over the canyons and slopes in a somewhat wide vicinity around Sedona, Arizona. It is distinguished from Hesperocyparis arizonica by its very smooth, non-furrowed bark which can appear in shades of pink, cherry, and grey.[3]

It is often seen in cultivation, as unlike the Monterey cypress, it has proved to be very resistant to cypress canker.[4]

Taxonomy

[edit]

Hesperocyparis glabra was scientifically described by George Bishop Sudworth in 1910 with the name of Cupressus glabra.[2][5] In 1966 the botanist Elbert Luther Little published a paper where he argued that it was a subspecies of what was then Cupressus arizonica.[2] Along with the other new world Cupressus species it was transferred to the new genus Hesperocyparis in 2009. At the same time the authors restored it as a species under its present name.[2][6]

As of 2024 Hesperocyparis glabra is listed as the accepted species name with no subspecies by Plants of the World Online (POWO),[2] World Flora Online,[7] and the USDA Natural Resources Conservation Service PLANTS database (PLANTS).[8]
