It was described in 1918 by John Frederick Bailey and Cyril Tenison White.[2] It is threatened by habitat loss. DescriptionA. microstachya grows up to about {{Convert|50|m|abbr = on}} in height and {{Convert|2.7|m|abbr = on}} 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.[4]DistributionIt has a very restricted distribution, being almost limited to the Atherton Tableland in Far North Queensland, with its elevational range {{Convert|400-900|m|abbr = on}} above sea level.[3] TimberThe 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 {{Convert|480|kg/m3|lb/ft3|abbr = on}}. It is not durable in contact with the ground, but can be used for house framing and flooring.[3] References1. ^{{ cite web |url={{IUCNlink|30536}} |title=Agathis microstachya In: IUCN 2009 |author=Conifer Specialist Group |work=IUCN Red List of Threatened Species Version 2009.1 |publisher=International Union for Conservation of Nature and Natural Resources |year=1998 |accessdate=September 22, 2009}} 2. ^1 {{ cite web |url=http://www.ipni.org:80/ipni/idPlantNameSearch.do?id=676649-1&back_page=%2Fipni%2FeditSimplePlantNameSearch.do%3Ffind_wholeName%3DAgathis%2Bmicrostachya%26output_format%3Dnormal |title=Plant Name Details for Agathis microstachya |publisher=IPNI |accessdate=September 22, 2009}} 3. ^1 2 Boland et al, p.38.
