Agathis microstachya, the bull kauri, is a species of conifer in the family Araucariaceae, endemic to Australia. It was described in 1918 by John Frederick Bailey and Cyril Tenison White.^[2] It is threatened by habitat loss.

Description

A. microstachya grows up to about 50 m (160 ft) in height and 2.7 m (8 ft 10 in) in diameter. The trunk is unbuttressed, straight and with little taper. Distinctive features are coarse, flaky bark, medium-sized cones with 160-210 scales, and leaves with numerous longitudinal, parallel veins.^[3]

Distribution

It has a very restricted distribution, being almost limited to the Atherton Tableland in Far North Queensland, with its elevational range 400–900 m (1,300–3,000 ft) above sea level.^[3]

Timber

The wood has an even texture, is easy to work and polishes well. The heartwood is cream to pale brown in colour. It is soft and light with a density of about 480 kg/m³ (30 lb/cu ft). It is not durable in contact with the ground, but can be used for house framing and flooring.^[3]
