Sequoia is a genus in the cypress family Cupressaceae, containing the single living species Sequoia sempervirens. Common names include Coast Redwood and California Redwood (it is one of three species of trees known as redwoods). It is an evergreen, long-lived, monoecious tree living for up to 2,000 years, and is commonly considered the tallest tree in the world, reaching up to 112 m (367 ft) in height and 7 m (23 ft) diameter at the base. It is thought to be named after the Cherokee Indian leader, Sequoyah, though this is uncertain.
