Bark grayish red-brown, breaking up into longitudinal thin shaggy flakes, flakes 1-2 cm. wide, 0.5 mm. thick; lenticels inconspicuous, outer bark 2-3 mm. in thickness, fibrous, with a reddish brown cross-section; newly formed periderm pale reddish brown; inner bark 2-6 mm. thick, pale reddish orange, immediately becoming pale yellowish brown after cutting, finely fibrous; cambium and newly formed phloem white in color. Branches terete, glabrous. Leaves coriaceous, alternate, lanceolate to linear-lanceolate, 6-8 cm long, 8-12 mm broad, straight or slightly falcate, dark green above, silver-green beneath, the base cuneate, acute or shortly attenuate; petioles very short, about 5 mm long.

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.
