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.
