Cedrus, with the common English name cedar, is a genus of coniferous trees in the plant family Pinaceae. They are native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean.
Thuja is a genus of coniferous tree or shrub in the Cupressaceae. There are five species in the genus, two native to North America and three native to eastern Asia. The genus is monophyletic and sister to Thujopsis. Members are commonly known as arborvitaes, thujas or cedars.
Cupressaceae is a conifer family, the cypress, with worldwide distribution. The family includes 27–30 genera, which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species.
Hesperocyparis macrocarpa also known as Cupressus macrocarpa, or the Monterey cypress is a coniferous tree, and is one of several species of cypress trees endemic to California.
Chamaecyparis lawsoniana, known as Port Orford cedar or Lawson cypress, is a species of conifer in the genus Chamaecyparis, family Cupressaceae. It is native to Oregon and northwestern California, and grows from sea level up to 4,900 feet (1,500 m) in the valleys of the Klamath Mountains, often along streams.
Platycladus is a monotypic genus of evergreen coniferous trees in the cypress family Cupressaceae, containing only one species, Platycladus orientalis, also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or Oriental thuja. It is native to northeastern parts of East Asia and North Asia, but is also now naturalised as an introduced species in other regions of the Asian continent.
Calocedrus, the incense cedar, is a genus of coniferous trees in the cypress family Cupressaceae first described as a genus in 1873. Three species are native to eastern Asia and one to western North America.
Libocedrus is a genus of five species of coniferous trees in the cypress family Cupressaceae, native to New Zealand and New Caledonia. The genus is closely related to the South American genera Pilgerodendron and Austrocedrus, and the New Guinean genus Papuacedrus, both of which are included within Libocedrus by some botanists. These genera are rather similar to the Northern Hemisphere genera Calocedrus and Thuja: in earlier days, what is now Calocedrus was sometimes included in Libocedrus. They are much less closely related, as recently confirmed. The generic name means "teardrop cedar", apparently referring to drops of resin.
Cupressus pygmaea, the Mendocino cypress or pygmy cypress, is a taxon of disputed status in the genus Cupressus endemic to certain coastal terraces and coastal mountain ranges of Mendocino and Sonoma Counties in northwestern California. It is a variable tree, and closely related to Cupressus abramsiana and Cupressus goveniana, enough to sometimes be considered conspecific with them.
Austrocedrus is a genus of conifer belonging to the cypress family (Cupressaceae). It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar. The generic name means "southern cedar".
Papuacedrus papuana is a species in the conifer family Cupressaceae, the sole species in the genus Papuacedrus. Some botanists do not consider this species as forming a distinct genus, but include it in the related genus Libocedrus. It is native to New Guinea and to the Indonesian Province of Maluku.
Phoradendron is a genus of mistletoe, native to warm temperate and tropical regions of the Americas. The center of diversity is the Amazon rainforest. Phoradendron is the largest genus of mistletoe in the Americas, and possibly the largest genus of mistletoes in the world. Traditionally, the genus has been placed in the family Viscaceae, but recent genetic research acknowledged by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae.
Calocedrus formosana is a conifer endemic to Taiwan.
Calocedrus macrolepis, commonly known as Chinese incense-cedar; is a species of conifer native to southwest China, northern Vietnam, northern Laos, extreme northern Thailand and northeastern Myanmar.
Libocedrus bidwillii, also called pāhautea, kaikawaka or New Zealand cedar, is a species of Libocedrus, endemic to New Zealand. It is in the cypress family Cupressaceae.
Libocedrus plumosa, with the common name kawaka, is a species of Libocedrus that is endemic to New Zealand.
Cupressus forbesii, now reclassified by some as Hesperocyparis forbesii, and with the common names Tecate cypress or Forbes' cypress, is a nonflowering, seed bearing tree species of cypress native to southwestern North America.
Phoradendron libocedri is a species of flowering plant in the sandalwood family known by the common name incense-cedar mistletoe. It is native to western North America from Oregon to Baja California, where it grows in forests on its host tree, the California incense-cedar.
Calocedrus huashanensis is an extinct incense-cedar species in the family Cupressaceae described from a group of isolated foliage fossils including stems and leaves. The species is known from Oligocene sediments exposed in the Guangxi Zhuang Autonomous Region, China. It is one of a number of extinct species placed in the living genus Calocedrus.
