![]() ![]() glyptostroboides is important to delimit management units and key germplasm resources. Distinguishing the genotypes of all wild individuals of M. The Story of the Discovery and Naming of Dawn RedwoodĬorvallis: tree in Riverfront Park, just south of the Harrison Ave. Metasequoia glyptostroboides is a living fossil and an endangered species listed in the International Union for Conservation of Nature (IUCN).Metasequoia flourished in the Miocene epoch of 25 to 5 million years ago and left its record embedded in rocks across the Oregon landscape. State Fossil of Oregon: The Oregon legislature designated the Metasequoia as the official state fossil in 2005. 'Miss Grace' - more or less ground sprawling, but if staked, a small tree with weeping branches.'Gold Rush' - bright yellow foliage in spring and retains much of the color throughout the summer.Several cultivars are available, including: Hardy to USDA Zone 4 Native to Sichuan (Szechuan, Szechwan), China. Easy to transplant, performs best in moist, well-drained, slightly acid soils. There were around 10 species in the Metasequoia. Pollination occurs in early spring and the seeds in the female cones are mature by the fall. (However, because of western Oregon's wet, but mild, winters, the cones are not dry enough to open and release the seeds until the following spring.) Metasequoia glyptostroboides Hu et Cheng is the only species in the genus Metasequoia Miki ex Hu et Cheng, which belongs to the Cupressaceae family. Juvenile growth of various tree species in the Copera afforestation trial. Journal of the Arnold Arboretum 64: 105128. The female (seed) cones are solitary, oval, green then light brown, about 2 cm long male (pollen) cones are arranged in long pendant clusters, each cone is globose and about 5 mm long. Metasequoia glyptostroboides Its present status in central China. Bark reddish brown when young, darker, fissuring, and exfoliating in strips when mature. The trees are monoecious, both male and female cones on an individual plant. Few researchers, however, have compared the genetic structure of restored and natural populations of threatened plant species. UNIV., NANKING, CHINA Dawn Redwood This dawn redwood is among the first of its kind to grow in North America in over two million years. Needles are arranged in opposite pairs, each is about 15 mm long, straight or slightly curved, bright green above, light green below. Abstract: Information on population genetics is fundamental to developing in situ or ex situ conservation strategies. 524-48AA Cupressaceae Metasequoia glyptostroboides SD - LINEAGE 524-48 - 1948 - 1948 W - WILD ORIGIN - CHINA - CHENG, W.C. Deciduous conifer, 70-100 ft (21-30 m), excurrent, pyramidal, flat topped when mature. ![]()
