Common name: Kauri Pine, Queensland Kauri or Smooth-barked Kauri 
 

Agathis robusta (syn. A. palmerstonii; Queensland Kauri or Smooth-barked Kauri) is a coniferous tree in the family Araucariaceae, native to eastern Queensland, Australia.  

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.  
The Queensland Kauri 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.

A native of Australia, Agathis robusta (C.Moore ex F.Muell) Bailley of the family Araucariaceae is known as Kauri Pine. It is a tall tree monoecious tree reaching up to 40m and unlike other conifers, has broad leaves resembling to Acacia auriculiformis.

It is a large evergreen coniferous tree, native to Australia.
It grows straight and tall to a height of 30-50 m, with smooth, scaly bark.
The leaves are elliptic, 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 round, 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

Yes a very handsome tree with similarity to dicot plants. We have few here in Pantnagar (Uttarakhand) but they never have cones.

Nice. There is one very interesting thing about vegetative propagation of this species.

It can be easily grown by the stem cuttings. Obviously you will not cut the main stem but the leafy branches. But no matter how you keep, the branches always behave as branches and they never stand up !!! ultimately looking like a strangler…
