Dacrycarpus dacrydioides, commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of 60 m and a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as Podocarpus dacrydioides, and was given its current binomial name Dacrycarpus dacrydioides in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera Dacrycarpus and Dacrydium. In traditional Māori culture, it is an important source of timber for the building of waka and making of tools, of food in the form of its berries, and of dye. When Europeans discovered it in the 18th century they found large remnant stands in both the North and South Islands, despite burning of forest by early Māori. Its use for timber and its damp fertile habitat, ideal for dairy farming, have led to its decimation almost everywhere except South Westland. Kahikatea seeds have fleshy structures called receptacles attached to them, which encourage birds such as kererū and tūī to eat them and disperse the seeds. The water storage ability of this structures may also be to protect seeds from drying out. It supports many smaller plants in its own branches, which are called epiphytes; 100 different species have been recorded on one tree alone. Description The kahikatea is a coniferous tree reaching a height of , making it the tallest New Zealand tree, with a trunk through. It has a 600 year life span and gains maturity after between 250 and 450 years. Near the base of the tree, the roots are typically buttressed and grooved. The wood itself is odourless and white. The majority of the trunk is branchless—in adults around three quarters—and has grey or dark grey coloured bark which falls off thickly in flakes. Young adults have no branches in a third to a half of the trunk and have a conic shape. In juveniles the leaves are 3–7 (reaching 4 mm in young adults) by 0.5–1 mm and a dark green to red colour that come to a marked point. They are narrow, arranged in almost opposite pairs spreading away from a wider base, and curved like a scythe. In adulthood the leaves change dramatically and are a brown-green colour and just 1–2 mm long,
