binomial_authority = HayataTaiwania ("Taiwania cryptomerioides") is a large coniferous
tree in the cypress familyCupressaceae , formerly listed in the segregate family Taxodiaceae. It is native to easternAsia , growing in themountain s of centralTaiwan , and locally in southwestChina and adjoiningMyanmar and northernVietnam . It is endangered byillegal logging for its valuablewood in many areas. It is very likely that the range was more extensive in the past before extensive felling for the wood.It is the largest tree in Asia, reported to heights of 80 m tall and with a trunk up to at least 3 m diameter. The leaves are needle-like or awl-like and 8-15 mm long on young trees up to about 100 years old, then gradually becoming more scale-like, 3-7 mm long, on mature trees. The cones are small, 15-25 mm long, with about 15-30 thin, fragile scales, each scale with two
seed s.The populations in mainland Asia are treated as a distinct species "Taiwania flousiana" by some botanists, but the claimed differences between these and the Taiwanese population are not consistent when a number of specimens from each area are compared.
The genus is named after the island of Taiwan, from where it first became known to the botanical community in 1910.
The wood is soft, but durable and attractively spicy scented, and was in very high demand in the past, particularly for
temple building andcoffin s. The rarity of the tree and its slow growth inplantation s means legal supplies are now very scarce; the species has legal protection in China.References
