Description

Lplumosa877
Young 'kawaka' tree.

Libocedrus plumosa is an evergreen coniferous tree growing to 30–35 metres (98–115 ft) tall, with a trunk up to 3 metres (9.8 ft) diameter. The bark is loose, fibrous and light brown.

The foliage is arranged in flattened sprays; the leaves are scale-like, arranged in opposite decussate pairs on the shoots; the facial leaves are 1–2 mm long and 1 mm broad, and the lateral leaves distinctly larger, 2–5 mm long and 1.5–2 mm broad.

The seed cones are cylindrical, 12–18 mm long, with four scales each with a prominent curved spine-like bract; they are arranged in two opposite decussate pairs around a small central columella; the outer pair of scales is small and sterile, the inner pair large, each bearing two winged seeds. They are mature about six to eight months after pollination. The pollen cones are 3–5 mm long.

Cultivation

The kawaka has been planted as an ornamental tree in several parts of the British Isles, including as far north as Castlewellan, Northern Ireland.
