Dacrycarpus dacrydioides 纽西兰鸡毛松

Photographie des cônes de Dacrycarpus dacrydioides.

Dacrycarpus dacrydioides or kahikatea (from its name in the Māori language) is a coniferous tree endemic to New Zealand.

The tree grows to a height of 55 metres (180 ft) with a trunk exceeding 1 metre (3 ft) in diameter, and is buttressed at the base. It is dominant in lowland forest and wetlands throughout the North and South Islands. The leaves are spirally arranged; on young plants, they are awl-shaped, 3 to 8 mm long, and twisted at the base to lie spread to the sides of the shoot in a flat plane; on mature trees, they are scale-like, 1 to 3 mm long, and placed all round the shoot. The cones are highly modified, with the cone scales swelling at maturity into an orange to red, fleshy, aril with a single apical seed 3 to 5 mm in diameter. The seeds are dispersed by birds, which eat the fleshy scale and pass the seeds in their droppings.
