In a Nutshell:
* Cupressus stephensonii is a species of conifer known as the Cuyamaca cypress, and is endemic to southern California. It has been classified as Hesperocyparis stephensonii. It was previously listed as Cupressus arizonica subsp. stephensonii and Cupressus arizonica var. glabra.
* The Cuyamaca Cypress exists only in the headwaters area of King Creek in the Cuyamaca Mountains of the Peninsular Ranges system, south of Cuyamaca Peak within San Diego County in extreme Southern California.
* It is an IUCN Red List Critically endangered species, and a California Native Plant Society Inventory of Rare and Endangered Plants listed Seriously endangered species. The entire native (world) population of the tree was reduced down to thirty to forty individual trees by the 2003 Cedar Fire.
* It can be hard to distinguish them, one of the main distinguishing characteristics is the color of the smooth bark on mature trees which varies from pink to grey to pure white, as well as the mature form which tends to be much more spreading than C. arizonica. more...
