Cupressus revealiana (Silba) Bisbee, comb. nova
validation as a new Cupressus species
with notes on identification and distribution of other nearby cypress species.
The northern Baja California Cypress was first described in 1981 by J. Silba as a variety
of Cupressus arizonica under the name C. a. var. revealiana. Later, Silba (2009) treated it as a
species but in the segregate genus Hesperocyparis, publishing the combination Hesperocyparis
revealiana. With the recent conclusion of monophyly of the genus Cupressus sensu lato (Mao et
al. 2009 ; Christenhusz et al. 2011), it is necessary to make the following new combination :
