Prumnopitys taxifolia, the mataī (Māori: mataī) or black pine, is an endemic New Zealand coniferous tree that grows on the North Island and South Island. It also occurs on Stewart Island/Rakiura (47 °S) but is uncommon there.
It grows up to 40 m high, with a trunk up to 2 m diameter. The leaves are linear to sickle-shaped, 10–15 mm long and 1.5–2 mm broad. The seed cones are highly modified, reduced to a central stem 3–4 cm long bearing 1-6 scales, each scale maturing berry-like, 10–15 mm long, violet-purple with a soft edible pulp covering the single seed. The seeds are dispersed by the New Zealand pigeon (kererū), which eats the 'berries' and passes the seeds in its droppings.
