Its improbable discovery in China in the 1940s is one of botany’s most romantic sagas, a romance that is only accentuated by this tree’s very special beauty. Metasequoia belongs to an elite group of plants – mostly quite unrelated – whose stories are the apogee of botanical legend. glyptostroboides will show variation, but in a case such as this it is neither helpful nor prudent to attempt to classify this variation too finely, and we follow others in consigning these names to synonymy. As with any species, seed-raised plants growing across such a vast range of climatic zones as M. Neither name is accepted at any rank by major treatments, including the Flora of China, Plants of the World Online, Farjon 2017, etc. In 2010 Silba resvied both names to subspecies rank. neopangea Silba described from material cultivated in the USA in 2001. Wu described from Chinese material in 1984 M. Taxonomic note Two synonyms have been treated here: M. Associates that continue to grow with Metasequoia in its moist microhabitats include species that can tolerate periodic flooding such as Liquidambar acalycina, Nyssa sinensis, and Pterocarya hupehensis. 70 years, especially on valley-floor sites, but fragments of native forest suggest that previously the wider forest featured multiple species of Quercus, Lindera, Prunus, Acer and Ilex, among others. The majority of the natural habitat has been heavily modified in the last c. Habitat A riparian species occuring on moist valley floors, or in deep ravines and other areas with seepage and hence constant moisture, 750–1500 m asl. Pollination Feb-Mar, before leaves, seed maturity Oct-Nov (China) seed cones maturing within one year. Seed cones terminal on leafy shoots 2–4(–8) cm long, purplish black when young, oblong-ellipsoid to 9 × 5.5 mm at pollination subglobose to 1.4–2.5 × 1.6–2.3 cm when mature with 8–12 opposite scale pairs. 4 × 3 mm, lowest minutely ciliate distally, others glabrous. Pollen cones ovoid, 2.5–5.5 × 2–3.8 mm bracts triangular-ovate or obovate, c. Leaves linear with an obtuse apex, 0.8–1.5 cm × 1.2–2 mm on old trees, larger on vigorous young trees, bluish- or greyish- or yellowish-green, turning bronzey yellow or more often orange or rust-red in autumn. Lateral branchlets opposite, deciduous, nodding or pendent, pinkish-green in active growth, soon maturing to bronzey-brown and then brownish-grey, resembling compound leaves, ovate-elliptic in outline 3–7 × 1.5–4 cm. First order branches long, ascending or nearly level, second order brances slender. Crown of young trees conical-pyramidal, broad-conical later. Bark of young trees pale orange-brown, occasionally darker in whole or in sections, irregularly exfoliating in fibrous strips in old trees brownish-grey. Tree to 50 m tall trunk variably flared and fluted at base, to 2.5 m dbh.
