Hesperocyparis
''Hesperocyparis'' (western cypress) is a genus of trees in the family Cupressaceae, containing North American species otherwise assigned to the genus ''Cupressus''. They are found throughout western North America. Only a few species have wide ranges, with most being restricted-range endemics. Taxonomy Members of ''Hesperocyparis'' were and still are placed in ''Cupressus'' by many authorities, but phylogenetic evidence supports a different affinity. A 2021 molecular study found ''Hesperocyparis'' to be the sister group to the genus '' Callitropsis'' (containing only the Nootka cypress), with this clade being sister to the Asian genus ''Xanthocyparis'', containing only the Vietnamese golden cypress. The clade comprising all three genera was found to be sister to a clade containing ''Juniperus'' and ''Cupressus sensu stricto''. If ''Hesperocyparis'' and the other smaller genera were reunited with ''Cupressus'' it may also require them to be merged into a larger genus including ...

Hesperocyparis Guadalupensis
''Hesperocyparis guadalupensis'', commonly known as Guadalupe cypress, is a species of western cypress from Guadalupe Island in the Pacific Ocean off the western coast of Mexico's Baja Peninsula. It was previously known as ''Cupressus guadalupensis'' until 2009. It is a medium-sized tree with fine green to blue-green foliage. In its native habitat it depends on water from the fogs that envelop high ground in the northern half of the island. It became an endangered species due to feral goats living on Guadalupe Island that – for more than a century – prevented new trees from growing. In 2005 the goats were finally removed from the tree's island home as part of an island restoration project. New trees are growing and other plants are beginning to recover, though the future of the species is not yet assured. Guadalupe cypress is closely related to the vulnerable Tecate cypress, which grows on the mainland in Baja California and southern California. It is used as an ornamental t ...

Hesperocyparis Macrocarpa
''Hesperocyparis macrocarpa'' also known as ''Cupressus macrocarpa'', or the Monterey cypress is a coniferous tree, and is one of several species of cypress trees native to California. The Monterey cypress is found naturally only on the Central Coast of California. Due to being a glacial relict, the natural distributional range of the species during modern times is confined to two small relict populations near Carmel, California, at Cypress Point in Pebble Beach and at Point Lobos. Historically during the peak of the last ice age, Monterey cypress would have likely comprised a much larger forest that extended much further north and south.Axelrod, D. I. (1982)Age and origin of the Monterey endemic area.''Madroño'', ''29''(3), 127–147. Description ''Hesperocyparis macrocarpa'' is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesperocyparis Lusitanica
''Hesperocyparis lusitanica'', the Mexican cypress, cedar-of-Goa or Goa cedar, is a species of cypress native to Mexico and Central America (Guatemala, El Salvador and Honduras). It has also been introduced to Belize, Costa Rica and Nicaragua, growing at altitude. The scientific name ''lusitanica'' (of Portugal) refers to its very early cultivation there, with plants imported from Mexico to the monastery at Buçaco, near Coimbra in Portugal in about 1634; these trees were already over 130 years old when the species was botanically described by Miller in 1768. In Mexico, the tree is also known as ''cedro blanco'' (white cedar) or ''teotlate''. Description ''Hesperocyparis lusitanica'' is an evergreen conifer tree with a conic to ovoid-conic crown, growing to 40 m tall. The foliage grows in dense sprays, dark green to somewhat yellow-green in colour. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots.

Hesperocyparis Montana
''Hesperocyparis montana'', commonly known as the San Pedro Mártir cypress or San Pedro cypress, is a species of conifer. It is a tree native to the Sierra de San Pedro Mártir of Baja California state in northwestern Mexico. Description ''Hesperocyparis montana'' is a tree that grows 5–20 meters in height. In exceptional cases the diameter of the trunk will reach one meter, but more typically will be 20–50 centimeters. The bark on the trunk has narrow ridges and comes off in strips and may be deep brown or red-brown in color. On younger specimens or on the branches the bark sheds large patches with smooth red-gray bark underneath. The bark of young twigs is gray. Seed cones are globose or ovoid, up to 30 mm long and brown or gray-brown when mature. Cones open at maturity in October and release 60 to 70 seeds, which are tan-colored and 3-4(-5) × 3-4 mm.

Hesperocyparis Glabra
''Hesperocyparis glabra'', known as the Arizona smooth bark cypress or smooth Arizona cypress, is a conifer native to the American Southwest, with a range stretching over the canyons and slopes in a somewhat wide vicinity around Sedona, Arizona. It is distinguished from '' Hesperocyparis arizonica'' by its very smooth, non-furrowed bark which can appear in shades of pink, cherry, and grey. It is often seen in cultivation, as unlike the Monterey cypress, it has proved to be very resistant to cypress canker. Taxonomy ''Hesperocyparis glabra'' was scientifically described by George Bishop Sudworth in 1910 with the name of ''Cupressus glabra''. In 1966 the botanist Elbert Luther Little published a paper where he argued that it was a subspecies of what was then ''Cupressus arizonica''. Along with the other new world ''Cupressus'' species it was transferred to the new genus ''Hesperocyparis'' in 2009. At the same time the authors restored it as a species under its present name.
