* Riparian habitats on valley floors and in moist ravine bottoms, on acidic, montane yellow-earth soils in regions with moderate climate,Ī rare species as a native plant because the valley floors are now largely under rice cultivation.Īlso widely cultivated as an ornamental or planted forĪfforestation in Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Liaoning, Shaanxi, Shandong, Shanxi, Sichuan, Yunnan, Zhejiang. Pollination Feb-Mar, before leaves, seed maturity Oct-Nov. Seed cones purplish black when young, oblong-ellipsoid and to 9 × 5.5 mm at pollination, subglobose and 1.4-2.5 × 1.6-2.3 cm when mature basal cone scales 9-ovulate, middle 7-ovulate, distal 5-ovulate, apical sterile. 4 × 3 mm, lowest minutely ciliate distally, others glabrous. It is a relative of both the giant sequoia and the coast redwood trees native to the United States. Dyeing onto cotton fiber was carried out. Pollen cones ovoid, 2.5-5.5 × 2-3.8 mm bracts triangular-ovate or obovate, ca. The dawn redwood, Metasequoia glyptostroboides, is a coniferous tree native to China. Abstract The aim of this study was to investigate the possibility utilizing Metasequoia (Metasequoia glyptostroboides) cone as a new natural dye resource. Leaves borne at 45-60° to branchlet axis, 2-5 mm apart, bluish green or yellowish green adaxially, paler abaxially, turning orange or red in autumn, linear, 0.8-1.5 cm × 1.2-2 mm on old trees but longer on younger trees, stomatal hands 0.4-0.6 mm, indistinct, marginal bands 0.5-0.6 mm wide, apex obtuse or with hyaline mucro, more sharply acute on leaves of leader branchlets. Then in the 1940s it was rediscovered in the Sichuan-Hubei region. Only fossil remains showed that its history stretches back into the Age of Dinosaurs. It was considerd to be extinct for million of years. It features an upright, narrowly conical form that. Although shortest of the redwoods, it grows to at least 200 ft in height. It is native to the SichuanHubei region of China.

Lateral branchlets deciduous, opposite, each subtended by leaflike scale, with longer and shorter leaves alternating irregularly, forming an ovate-elliptic outline 3-7 × 1.5-4 cm. Metasequoia glyptostroboides, also known as Dawn redwood or Water fir, is the last living species in its genus. Metasequoia glyptostroboides (Dawn Redwood) is a large deciduous coniferous tree of great beauty. Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered coniferous tree, the sole living species of the genus Metasequoia, one of three species in the subfamily Sequoioideae.

bark of young trees pale orange-brown with darker flakes and exfoliating, finally dark reddish brown to gray, fissured crown narrowly conical or pyramidal, finally broadly conical branches ascending branchlets pendulous, axis pinkish green or pale purple in 1st year, later brownish gray winter buds to 5 × 3 mm, apex obtuse, scales yellowish brown, ca. Trees to 50 m tall trunk buttressed at base, to 2.5 m d.b.h.
