Dacrydium cupressinum, commonly known as rimu, is a large evergreen coniferous tree endemic to the forests of New Zealand. It is a member of the southern conifer group, the podocarps.

The Māori name rimu comes from the Polynesian term limu which the tree's foliage were reminded of, ultimately from Proto-Austronesian *limut meaning "moss". The former name "red pine" has fallen out of common use.

Description

Rimu is a coniferous tree with dark red wood that reaches a height of 35–60 m (115–197 ft), with a trunk 1.5–2 m (4.9–6.6 ft) in diameter. The bark is flaky and dark-brown in colour. In its juvenile stages the branches are thin and numerous, but as the tree grows older around three quarters of the tree becomes branchless. It has a lifespan of 600–800 years, but may reach beyond 1000 in rare cases.

The yellowish-green foliage varies in size and shape between the juvenile, sub-adult, and adult life stages. The leaves begin 0.4–10 mm (0.016–0.394 in) long and 0.5–0.1 mm (0.0197–0.0039 in) wide with sharp points. They are divided along an axis and roughly shaped like a sickle. In sub-adults the leaves shorten to 4–6 mm (0.16–0.24 in) long, curve upward, and become diamond shaped. In adults the leaves become smaller, just 2–3 mm (0.079–0.118 in) long, and press against one-another tightly.

Male and female cones, or strobili, appear first in sub-adults but on different male and female trees. Male cones are 5–10 mm (0.20–0.39 in) long, rectangular shaped, and covered in a yellow pollen. Ovules appear on their own on upturning branchlets. The fruit consists of a 1–2 mm (0.039–0.079 in) long fleshy orange receptacle and a 3–4 mm (0.12–0.16 in) long dark brown rectangular-shaped seed. Rimu is distinctive enough that it is unlikely to be misidentified except as a seedling with Manoao colensoi, which have glossier, less fine leaves. It has a diploid chromosome count of 20.
