The Paiute cypress grows in a small area of the Southern Sierra Nevada, within Kern County, California and Tulare County. It is found on soils of granitic origin at altitudes of 3,000–6,000 feet (910–1,830 m). It is found in pinyon/juniper and oak/pine woodlands, chaparral, and closed-cone-cypress forest habitats. [2]
Hesperocyparis arizonica was given its first scientific name and described by Edward Lee Greene in 1882 as Cupressus arizonica, placing it in genus Cupressus. [3] [5] This description was soon after disputed by Maxwell T. Masters who, in 1896, published a journal article where he said it should be considered a subspecies of Cupressus benthamii with the variety name of arizonica. [3]
Inside the cone are approximately 70 to 100 seeds, brown with a light waxy coating described by botanists as glaucous. [3] [10] The seeds are much larger than those of other western cypress trees, weighing two to seven times as much. [4] Closed, but already ripe, cones still on the trees will also open after being exposed to the heat of a fire ...
The male cones are 3–5 mm long and release highly allergenic pollen in late winter. The cones of C. sempervirens can withstand years of being sealed and are known to perform serotiny. [8] The tree is moderately susceptible to cypress canker, caused by the fungus Seiridium cardinale, and can suffer extensive dieback where

The cones remain closed for many years, only opening after the parent tree is killed in a wildfire, thereby allowing the seeds to colonize the bare ground exposed by the fire. The male cones are 3–5 mm (0.12–0.20 in) long, and release pollen in February/March. Typically cones of H. goveniana are smaller than those of H. macrocarpa.
