Meryta sinclairii

Meryta sinclairii (puka or pukanui) is a large-leaved evergreen tree endemic to New Zealand that grows to about 8 m tall, with the distinctly tropical appearance typical of the genus. There are about 27 species of Meryta, all small, resinous trees of the subtropical and tropical Pacific Ocean.

Puka occurs naturally on the Three Kings Islands (c. 34°S, 172°W) and the Hen and Chickens Islands (c. 36°S, 175°W) where it occurs in greater abundance in the relatively sheltered valleys, where soils are thick and conditions are relatively moist, rather than on the exposed ridge-tops. However, puka can also grow on cliffs with shallow, stony soils which suggests some tolerance of drought.

Description

The elliptical, thick, leathery leaves may be up to 50 cm long and 20 cm wide with a glossy upper surface. They are the largest entire leaves in the New Zealand flora. The petioles (leaf stalks) may be up to 35 cm long. The tree produces panicles of green-white flowers followed by black berries. The leaves are densely crowded, twenty to thirty together at the tips of the branches, with a few large deciduous scales amongst the petioles of the youngest.
