Metasequoia, a living fossil, an update of native and cultivated (1948 to 2008).
The discovery of extant material of the "Living Fossil", Metasequoia glyptostroboides, from China in the 1940s was one of the greatest botanical discoveries of the twentieth century. This report summarizes both the native and cultivated situation of this living fossil for the first time in sixty years (1948-2008). There are 5391 native trees within an area about 600 kmĀ² in east Sichuan and west Hubei in central China today, but only five trees are in the neighboring Hunan province. Cultivated trees have been found in fifty countries in every continent. The best growth is in USDA Plant Hardiness Zones 5-9 in North America and Europe as well as similar areas in East Asia. The tallest individual is about 38 meters, and the largest is about 6.2 meters in girth.
