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. 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''. This genus contains the following species: *'' Hesperocyparis abramsiana'' (C. B. Wolf) Bartel *''Hesperocyparis arizonica'' (Greene) Bartel *''Hesperocyparis baker ...

Hesperocyparis Stephensonii
''Cupressus stephensonii'' is a species of conifer known as the Cuyamaca cypress, and is endemic to Southern California. It has been classified as ''Hesperocyparis stephensonii''. It was previously listed as ''Cupressus arizonica'' subsp. ''stephensonii'' and ''Cupressus arizonica'' var. ''glabra''. Distribution The Cuyamaca Cypress exists only in the headwaters area of King Creek in the Cuyamaca Mountains of the Peninsular Ranges system, south of Cuyamaca Peak within San Diego County in extreme Southern California. Trees were reported growing as low as in elevation in 1998, but the presence of these individuals today has not been verified. Most individual trees occur at within the Pacific Southwest Research Station's King Creek Research Natural Area, in the Cleveland National Forest. Conservation It is an IUCN Red List Critically Endangered species, and a California Native Plant Society Inventory of Rare and Endangered Plants listed Seriously endangered species.

Hesperocyparis Macrocarpa
''Hesperocyparis macrocarpa'' is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California. The Monterey cypress is found naturally only on the Central Coast of California. 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 meters (133 feet) in perfect growing conditions, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthocyparis
''Xanthocyparis'' is a genus of cypresses in the family Cupressaceae. , it has only one species, ''Xanthocyparis vietnamensis'', native to Vietnam and southeast China. It is commonly known as the Vietnamese golden cypress. The Nootka cypress, ''Cupressus nootkatensis'' or ''Callitropsis nootkatensis'', was also placed in the genus, but this has been rejected. Taxonomy In 2002, Aljos Farjon and others described the new genus ''Xanthocyparis'' to accommodate the new Vietnamese species '' X. vietnamensis'' and another species, the Nootka cypress, which had been formerly included in the genus ''Chamaecyparis'' as ''C. nootkatensis''. This was based in part on the discovery that ''C. nootkatensis'' was more closely related to the genus ''Cupressus'' than to ''Chamaecyparis''. In 2004, Damon Little and others, while confirming the above relationship with further evidence, pointed out that as circumscribed by Farjon ''et al.'', ''Xanthocyparis'' included the type species ...
