The currently accepted scientific name of Gowen cypress is Cupressus goveniana Gord. (Cupressaceae) [1,5,12,13]. There are two recognized subspecies [5,30]: C. goveniana ssp. goveniana Gord. Gowen cypress C. goveniana ssp. pygmaea (Lemm.) Bartel Mendocino or pygmy cypress As used in this write-up, "Gowen cypress" refers to both subspecies unless C. goveniana ssp. goveniana is specifically indicated. Mendocino cypress was previously considered a variety of Gowen cypress, but has been given subspecies status by J. Bartel . Santa Cruz cypress (C. abramsiana), listed as a variety of Gowen cypress by Wolf  and Little , has since been given species status by Hickman .
