The Dawn Redwood ("Metasequoia glyptostroboides") is a deciduous conifer endemic to the Daba Shan, whose nearest living relatives are the Coast Redwood and Giant Sequoia of California. Redwoods formerly ranged across the northern hemisphere, but were thought to be extinct outside California until stands of Dawn Redwood were discovered in the Daba Shan in the 1940s.
