Taxodium / t æ k ˈ s oʊ d i ə m / [1] is a genus of one to three species (depending on taxonomic opinion) of extremely flood-tolerant conifers in the cypress family, Cupressaceae. The name is derived from the Latin word taxus , meaning " yew ", and the Greek word εἶδος ( eidos ), meaning "similar to."
The largest dawn redwood recorded was an isolated specimen in China about 50 meters (160 feet) tall and 2.2 meters (7.2 feet) wide. This tree was killed by a lightning strike in 1951. [18] Several dawn redwoods of this height still live in the eastern part of Metasequoia Valley, where the tree was discovered.
The bark and foliage are similar to Sequoia, but Metasequoia is deciduous like Taxodium distichum (bald cypress), and, similarly, older specimens form wide buttresses on the lower trunk. It is a fast-growing tree to 130–150 feet (40–45 m) tall and 6 feet (2 m) in trunk diameter in cultivation so far (with the potential to grow even higher).
It is a medium-sized to large tree, reaching 30 m (98 ft) tall and with a trunk diameter of up to 1 m (3.3 ft), possibly more.The leaves are deciduous, spirally arranged but twisted at the base to lie in two horizontal ranks, 5–20 mm (0.20–0.79 in) long and 1–2 mm (0.039–0.079 in) broad, but 2–3 mm (0.079–0.118 in) long and scale-like on shoots in the upper crown.
Taxodium is an aquatic tree genus with roots that form knees in some species. ... [35] in eastern China [36] Deciduous unisexual trees with fan-like leaves.
Glyptostrobus is a small genus of conifers in the family Cupressaceae (formerly in the family Taxodiaceae).The sole living species, Glyptostrobus pensilis, is native to subtropical southeastern China, from Fujian west to southeast Yunnan, and also very locally in northern Vietnam and Bolikhamsai province of eastern Laos near the Vietnam border.
Many of the species are important timber sources, especially in the genera Calocedrus, Chamaecyparis, Cryptomeria, Cunninghamia, Cupressus, Sequoia, Taxodium, and Thuja. Calocedrus decurrens is the main wood used to make wooden pencils, and is also used in chests, paneling, and flooring. [ 20 ]
Like living Metasequoia and similar to M. occidentalis, M. heerii was deciduous.The foliage consists of branchlets with oppositely arranged leaves. The leaves are ovate to linear in shape, ranging from 6–25 mm in length and .8–1 mm in width, with a petiolate base, a distinct mid-vein, and an acute to obtuse tip.
