Sequoia, Sequoya or Sequoyah refers to a type of tree in the cypress family which includes the redwood trees. By extension the name may refer to:

<i>Sequoiadendron giganteum</i> Species of tree native to North America

Sequoiadendron giganteum, also known as the giant sequoia, giant redwood, Sierra redwood or Wellingtonia is a coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the most massive trees on Earth. They are native to the groves on the western slopes of the Sierra Nevada mountain range of California but have been introduced, planted, and grown around the world.

<i>Metasequoia</i> Genus of conifers

Metasequoia, or dawn redwood, is a genus of fast-growing coniferous trees, one of three species of conifers known as redwoods. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. Although the shortest of the redwoods, it grows to at least 165 feet in height. Local villagers refer to the original tree from which most others derive as Shuǐshān (水杉), or "water fir", which is part of a local shrine. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental, with examples found in various parks in a variety of countries. The genus was dominant near the North Pole during the Cretaceous.

<span class="mw-page-title-main">Cupressaceae</span> Cypress family of conifers

Cupressaceae or the cypress family is a family of conifers. 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. The family reached its peak of diversity during the mesozoic era.

The Giant Sequoia National Monument is a 328,000-acre (512 sq mi) U.S. National Monument located in the southern Sierra Nevada in eastern central California. It is administered by the U.S. Forest Service as part of the Sequoia National Forest and includes 38 of the 39 Giant Sequoia groves that are located in the Sequoia National Forest, about half of the sequoia groves currently in existence, including one of the ten largest Giant Sequoias, the Boole Tree, which is 269 feet (82 m) high with a base circumference of 112 feet (34 m). The forest covers 824 square miles (2,130 km2).

<i>Enchodus</i> Extinct genus of ray-finned fishes

Enchodus is an extinct genus of aulopiform ray-finned fish related to lancetfish and lizardfish. Species of Enchodus flourished during the Late Cretaceous, and there is some evidence that they may have survived to the Paleocene or Eocene; however, this may just represent reworked Cretaceous material.

<i>Athrotaxis</i> Genus of conifers

Athrotaxis is a genus of two to three species of conifers in the cypress family, Cupressaceae. The genus is endemic to western Tasmania, where they grow in high-elevation temperate rainforests.

Pyrophytes are plants which have adapted to tolerate fire.

Redwood Mountain Grove is the largest grove of giant sequoia trees on earth. It is located in Kings Canyon National Park and Giant Sequoia National Monument on the western slope of California's Sierra Nevada. The grove contains the world's tallest giant sequoia. The Hart Tree and Roosevelt Tree grow in the grove and are two of the 25 largest trees by volume in the world. The largest tree is the General Sherman Tree in the Giant Forest grove to the southeast.

The sequoia slender salamander is a species of salamander in the family Plethodontidae. It is endemic to California, in Tulare County in the western United States.

<i>Axelrodichthys</i> Extinct genus of coelacanths

Axelrodichthys is an extinct genus of mawsoniid coelacanth from the Cretaceous of Africa, North and South America, and Europe. Several species are known, the remains of which were discovered in the Lower Cretaceous (Aptian-Albian) of Brazil, North Africa, and possibly Mexico, as well as in the Upper Cretaceous of Morocco (Cenomanian), Madagascar and France. The Axelrodichthys of the Lower Cretaceous frequented both brackish and coastal marine waters while the most recent species lived exclusively in fresh waters. The French specimens are the last known fresh water coelacanths. Most of the species of this genus reached 1 metre to 2 metres in length. Axelrodichthys was named in 1986 by John G. Maisey in honor of the American ichthyologist Herbert R. Axelrod.

S. giganteum may refer to:

<span class="mw-page-title-main">Sequoioideae</span> Subfamily of coniferous trees (redwoods)

Sequoioideae, commonly referred to as redwoods, is a subfamily of coniferous trees within the family Cupressaceae, that range in the northern hemisphere. It includes the largest and tallest trees in the world. The trees in the subfamily are amongst the most notable trees in the world and are common ornamental trees. The subfamily reached its peak diversity in the early cenozoic.

<i>Sequoia</i> (genus) Genus of conifers in the cypress family Cupressaceae

Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. The two other genera in the subfamily Sequoioideae, Sequoiadendron and Metasequoia, are closely related to Sequoia. It includes the tallest trees, as well as the heaviest, in the world.

<i>Sequoiadendron chaneyi</i> Extinct species of conifer

Sequoiadendron chaneyi is an extinct species of tree in the Cupressaceae genus Sequoiadendron. Known from Miocene fossils found in Nevada and California, S. chaneyi is the oldest species of Sequoiadendron. The common use of the name "sequoia" generally refers to Sequoiadendron giganteum, which occurs naturally only in the various groves that exist on the western slopes of the Sierra Nevada of California. S. chaneyi is considered the probable direct ancestor to the extant Sequoiadendron giganteum.

The two giant sequoias near Kölpin in the parish of Demen in the district of Ludwigslust-Parchim in the German state of Mecklenburg-Vorpommern, are a natural monument. They belong to the species commonly known as giant sequoia, but also Wellingtonia and Sierra redwood.

<i>Sequoia affinis</i> Extinct species of conifer

Sequoia affinis is an extinct species of the genus Sequoia in the cypress family Cupressaceae.

Black Mountain Grove is a giant sequoia grove containing more than 150 relatively young trees located in a ravine on the southwestern slope of Black Mountain, a minor peak of the San Jacinto Mountains in Riverside County, California.
