as well ashe Cupressus Sargentii is commonly known as the Sargent Cypress.
The currently accepted scientific name of Sargent cypress is Cupressus sargentii Jeps. (Cupressaceae) . There are two recognized varieties : Cupressus sargentii var. sargentii Cupressus sargentii var. duttonii Jeps. Natural hybridization between Sargent cypress and MacNab cypress (Cupressus macnabiana) has been hypothesized, but evidence for it is inconclusive . Sargent cypress occurs only in California and has the widest distribution of all of the coastal California cypress . Numerous scattered groves occur in the Coast Ranges from northern Mendocino County south to Santa Barbara County . Sargent cypress is cultivated in Hawaii . Sargent cypress is a component of the northern interior cypress forest. This community is an open, fire-maintained, scrubby forest similar to the knobcone pine (Pinus attenuata) forest. Sargent cypress occurs in widely scattered, isolated groves throughout its range. It occurs in dense thickets as well as in open groves and sparse stands . Dense thickets are common in burned areas . Sargent cypress is associated with serpentine chaparral, and intergrades on less severe sites with upper Sonoran mixed chaparral, montane chaparral, or knobcone pine forest community types. On more mesic sites the northern interior cypress forest intergrades with mixed evergreen forest or montane coniferous forest . Sargent cypress is associated with redwood (Sequoia sempervirens)-Douglas-fir (Pseudotsuga menziesii) forest and associated North Coast forests in Mendocino County, California . It is commonly associated with chaparral and gray pine (Pinus sabiniana) throughout its range . In some areas, Sargent cypress is associated with yellow pine (Pinus ponderosa and P. jeffreyi) forests, closed-cone coniferous woodlands, and pine-cedar-cypress pygmy forests . Sargent cypress occurs sympatrically with MacNab cypress in Lake County, California, where it is larger and tends to occupy lower slopes than MacNab cypress .
