It belongs to the
Taxodiaceae Family, with the Latin name of Metasequoia glyptostroboides.
The deciduous
megaphanecophyte grow up to 35 to 42 meters high, with a chest diameter of 1.6
to 2.4 meters. It has taupe bark cracking into strips and swells at the bottom
of the trunk. The boughs stretch slantingly upward. The 1-year twigs are light
gray while the winter buds have white marks of short branchlet on the top or
their sides. The leaves are soft and linear, penniformly lined on lateral
branches. It is a kind of monoecious plant with subsphaeroidal sagging cones
that ripen in the same year, whose seeds are flat and obovoid, with wings
around.
It usually grows in
warm and moist places, where it is cool in summer and snowy but not freezing in
winter. It prefers the acidic mountain yellow earth, purple soil or alluvia,
with the pH value of 4.5 to 5.5. It is always found in the valleys at an
altitude of 800 to 1,200 meters, or the moist or slightly waterlogged piedmonts
with a gentle landform and deep and thick soil layer. It is a photophilous
plant, with developed root system and intumescence or longitudinal ridges in the
bottom of the trunk. The soil moisture determines its growing speed; therefore
there is a slow growth in the places poorly drained. It has its florescence in
the last ten days of February, and the cones ripen from the last ten days of
October to November.
It is distributed over the borderland of
Hubei, Sichuan and Hunan provinces. This world-renowned
plant is a peculiar mono-genus Chinese plant.
Being graceful in appearance, it can be used for courtyard greening and
ornamental purposes. Moreover, with a fast growing, strong adaptability and
vegetative propagation, it could be used for speedy and prolific
forestation.
