Unfortunately, while he collected some plant material, he did not attempt to identify or publish his findings. Though unaware of Miki's new genus, he recognized the unique traits of the tree. In the same year, Kan Duo (Toh Kan, 1903-1961), professor of Forest Management, National Central University, Chongqing, (formerly Chungking) observed an enormous living specimen while performing a survey in Sichuan and Hubei provinces. He realized he had discovered a new genus, which he named Metasequoia, meaning 'like a sequoia'. Shigeru Miki from Kyoto University identified a divergent leaf form. While studying fossil samples of the family Cupressaceae, Dr. When the genus Metasequoia was first described in 1941, it was from Mesozoic Era fossils, none of which were less than 150 million years old. Metasequoia glyptostroboides (dawn redwood) bonsai treeДЄlthough it was commonly known from the fossil record from across the northern hemisphere, the dawn redwood was considered extinct until the mid-twentieth century.

If the species had been discovered later, it might have become extinct before being investigated. The tree faces considerable risks of extinction in its wild range due to deforestation, however it has been planted extensively in arboreta worldwide, where it has proved a popular and fast-growing ornamental plant. It is a particularly well-known example of a living fossil species. In 1941, the genus Metasequoia was reported by paleobotanist Shigeru Miki as a widely distributed extinct genus based on fossils, before attracting considerable attention a few years later when small populations were found alive in central China.

Although the shortest of the redwoods, it can grow to 120В ft (37В m) in height. It now survives only in wet lower slopes and montane river and stream valleys in the border region of Hubei and Hunan provinces and Chongqing municipality in south-central China, notably in Lichuan county in Hubei. It is the sole living species of the genus Metasequoia, one of three genera in the subfamily Sequoioideae of the family Cupressaceae. Silverton, Oregon: Oregon Garden - Conifer Garden.Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered deciduous conifer. It is more likely that this narrative describes the origin of the cultivar 'Gold Rush', which has golden-yellow foliage throughout the summer. and renamed 'Miss Grace' this is unlikely since 'Miss Grace' does not have yellow foliage. Later it was brought to Europe by the Dutch nurseryman Pieter Zwijnenburg Jr.

Some nursery descriptions say it was originally discovered as a seedling in Japan and named 'Golden Ogi' ('golden mantle'). There is some confusion in the nursery literature about the origin of this cultivar, or rather its confusion with another cultivar. Hardy to USDA Zone 5 Discovered as a witch's broom in New York, it was introduced by Buchholz & Buchholz Nursery, in Gaston, Oregon. Easy to transplant, performs best in moist, well-drained, slightly acid soils. Foliage is gray-green in summer and orange in autumn prior to leaf fall. Deciduous conifer, more or less ground sprawling, but if staked, a small tree, maybe 10 ft and 3 ft wide ( 3 Г— 0.9 m) in 10 years, with weeping branches.
