Class: Pinopsida
Order: Pinales

Binomial name: Agathis robusta
Synonym: A. palmerstonii
Common name: Queensland Kauri, Smooth-barked Kauri, Dundathu Pine.
Agathis robusta is a coniferous tree in the family Araucariaceae, native to eastern Queensland, Australia. It is found in two disjunct areas, one in S Queensland between Tewantin and Maryborough (mainland) and on Fraser Island [latitude 25°-26.5° S]; the other in N Queensland between the Herbert River and Big Tableland near Cooktown [latitude 15.5°-18.5° S].
It is a large evergreen tree growing straight and tall to a height of 30-50 m, with smooth, scaly bark. The leaves are 5-12 cm long and 2-5 cm broad, tough and leathery in texture, with no midrib; they are arranged in opposite pairs (rarely whorls of three) on the stem. The seed cones are globose, 8-13 cm diameter, and mature in 18-20 months after pollination; they disintegrate at maturity to release the seeds. The male (pollen) cones are cylindrical, 5-10 cm long and 1-1.5 cm thick.
A. robusta was heavily logged in the past, and spectacular trees of prodigious size are much rarer than in pre-European times; despite this, the species as a whole is not endangered.
