Discussion

The geographically most restricted taxon recognized here, Cupressus macrocarpa is confined today to two picturesque groves near Monterey, but it is also known from fossils to have been in other regions. It is much planted and commonly naturalized near the coast from central California north to Washington and in warm temperate and subtropical regions worldwide.

Of conservation concern.

Bark texture and foliage features have been used to distinguish geographic varieties or segregate species. Although bark texture may be consistent within populations, over the species as a whole there is complete intergradation between smooth and fibrous barks. Various forms are commonly cultivated and sometimes persistent in the southern United States.
