Sequoia sempervirens
Sequoia sempervirens (sɛkwɔɪ.ə ˌsɛmpərˈvɪrənz)[1] is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, giant redwood and California redwood. It is an evergreen, long-lived, monoecious tree living 1200 — 1800 years or more[2]. This species includes the tallest trees on Earth, reaching up to 115.61 metres (379.30 ft) in height and up to 7.9 metres (25.9 ft) diameter at breast height. Before commercial logging and clearing began by the 1850's, this massive tree occurred naturally in an estimated 2.1 million acres along much of coastal California and the southwestern corner of coastal Oregon within the United States.
The name sequoia is sometimes used as a general term for the subfamily Sequoioideae in which this genus is classified, together with Sequoiadendron (Giant Sequoia) and Metasequoia (Dawn Redwood). Though it is one of three species of trees referred to as redwoods, use of the term redwood (alone) generally refers to this species more than the other two.
