Chaney, a paleobotanist at the University of California, during an expedition to China earlier in the year. The article further states that the seeds were collected by Ralph W. According to Dilworth the ancient trees would soon be growing in the Peavy arboretum north of Corvallis. Dilworth, assistant professor of forest management, recently received a packet of dawn redwood seeds from Arnold Arboretum, Jamaica Plains, Massachusetts. The Daily Barometer (June 3, 1948) reported that Professor J.R. campus: two trees, young and older, northeast of Community Hall The Story of the Discovery and Naming of Dawn RedwoodĬorvallis: tree in Riverfront Park, just south of the Harrison Ave.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. 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.) 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. 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. Needles are arranged in opposite pairs, each is about 15 mm long, straight or slightly curved, bright green above, light green below. Deciduous conifer, 70-100 ft (21-30 m), excurrent, pyramidal, flat topped when mature.Glyptostroboides was discovered as an extant plant, the botanists who described it and those who were associated with its introduction and distribution often referred to it as a 'living fossil. The genus Metasequoia Miki was first described from Lower Pliocene fossil material from Japan (Miki, 1941). It is grown for its conical form, interesting orangish brown bark, and soft, bright green leaves. Glyptostroboides was discovered in the wild in China in 1941, and it is the only species in this genus. The Metasequoia genus has been preserved in fossils as old as 50 million years. This list is certainly not exhaustive - additional taxa may be available in the trade, or may have been removed from our collection and thus removed from this list. The following species and varieties are currently (or recently were) in the collections at Boone County Arboretum.
