Common Names

Formosan cypress (6), Formosan false cypress (4), Taiwan cypress (7).

Taxonomic notes

Closely allied to Ch. pisifera, from which it differs in its more oblong cones (not globose), with the scales flat or slightly protuberant, not depressed in the centre.

Description

A tree attaining huge size in Taiwan, up to 65 m. Bark more or less red-brown. Branchlets in a horizontal plane. Shoots flattened. Leaves scale-like, shortly mucronate, triangular, upper surface green, whitish below, lateral scales of the same length as the facial ones, which have a glandular pit each; when crushed, foliage has an odour of rotting seaweed. Mature cones elliptic, 7-10(-12) mm long, 6-8(-9) mm across, composed of 10 to 14 scales with the outer surface brown, wrinkled and flat or slightly protuberant in the centre. Seeds 3 mm wide and brown, 2 on each scale (4, 8).

Range

Taiwan. Mountainous regions in the north and central parts of the island at 1000-3000 m, often forming pure stands or mixed with C. obtusa var. formosana (3). Kaoxiung & Taichung Xians, 24°17' to 24°23'N by 120°58' to 121°21'E, in coniferous and broadleaf mixed forest (2). USDA hardiness zone 8.

Big Tree

Diameter 582 cm, height 49.4 m, on Mount Morrison (5).

Oldest

"This species can attain 1500 years of age, and the oldest tree in Taiwan is about 3000 years old" (4). This is an extraordinary age to cite without supporting data, and must for now be regarded as dubious.
