The Modoc cypress, C. bakerii, is restricted to the Siskiyou and Shasta Counties of northern California, where it occurs on dry, inland slopes. The species was named after Milo Baker, the Californian botanist who discovered it in the late 19th century. It grows to about 30m and its globular cones take two years to develop. Rare in cultivation, it is the hardiest of the New World Cupressus. The subspecies mathewsii comes from the northern end of the Siskiyou Mountains, but is not considered sufficiently distinct to merit separate taxonomic recognition. Growth is good, but root anchorage may be a problem here in the Arboretum’s heavy soil.
