Description. Formosan cypress is a slow-growing, but long-lived and ultimately large to very large coniferous tree growing to 175 to 200 feet (55 – 60 m) tall with a trunk up to 22 feet (7 m) in diameter. The bark is red-brown, vertically fissured and has a stringy texture. The foliage is arranged in flat sprays; adult leaves are scale-like, 0.08 inch (1–3 mm) long, with pointed tips, green both above and below with only an inconspicuous stomatal band at the base of each scale-leaf; they are arranged in opposite decussate pairs on the shoots. The juvenile leaves, found on young seedlings, are needle-like, 0.15 to 0.3 inch (4 – 8 mm) long, soft and glaucous bluish-green. The seed cones are ovoid-oblong, 0.25 to 0.5 inch (6–12 mm) long and 0.15 to 0.3 inch (4 – 8 mm) in diameter, with 8–16 scales arranged in opposite pairs, maturing in autumn about 7–8 months after pollination. It is most closely related to the Japanese species, Chamaecyparis pisifera (Sawara Cypress), which differs in smaller globose cones 0.15 to 0.3 inch (4–8 mm) long with 6–10 scales.

Distribution. This species it native to Taiwan, where it grows in the central mountains at moderate to high altitudes of 3,200 to 9,200 feet (1,000 – 2,900 m) of elevation. It is threatened by habitat loss and over-cutting for its valuable timber.
