Montrouziera cauliflora, the giant Houp tree, is a very large forest tree endemic to New Caledonia, reaching up to 30 m tall with a straight trunk. It is not a plant for home growing; the key to its survival is intact moist evergreen forest.
Montrouziera cauliflora, the giant Houp tree, is a species of flowering plant in the family Clusiaceae. It is found only in New Caledonia, and is one of the largest trees in the seasonal tropical forests there. It is found in moist evergreen dense forest of low and medium elevation (between 200 and 1100 m) on all types of soil. The tree has a straight trunk, slightly conical, without buttresses but with a slightly wider base, up to 30 m high and 3 m in diameter (bigger trees are often hollow), with branches protruding horizontally. Houp trees make fruit but it is not edible by humans. Damage causes the bark to exude a yellow resin, thick and sticky, with no peculiar smell. The bark is dark gray or reddish for individuals in very dense forest, with deep vertical cracks.
