Sequoia tree
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 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 115.5 m (378 ft) in height and 7 m (23 ft) diameter at the base. The largest Sequoia tree in volume is the "Del Norte Titan", with an estimated volume of 1044.7 m³; it is 93.57 m tall with a diameter of 7.22 m. Among current living trees only 15 Giant Sequoias are larger than this; these are shorter, but have thicker trunks, giving the largest Giant Sequoia, General Sherman, a volume of 1,487 cubic metres (52,510 cubic feet).
