Distribution and Ecology

Taiwan: "the northern and central parts of the island, scattered in broad-leaved forests" (Li 1975).

The IUCN reports that this species is facing a very high risk of extinction in the wild in the near future, due to recent and ongoing exploitation within a range that is already severely fragmented, with total population size estimated at fewer than 2,500 mature plants and no subpopulation containing more than 250 mature plants.
