Distribution and Ecology

Australia: N Queensland, Bellenden Ker Range, at 900-1500 m elevation (Silba 1986). You can also create a highly detailed map, and access specimen data, using the "search" function at the Australia Virtual Herbarium.

The WCMC found that "Wherever logging is allowed exploitation has been very heavy and populations have declined. A large percentage of the forests is now protected."

Big tree





Best seen in Wurunuru National Park. I don't have a precise location but supposedly it can be seen along a popular waterfall hike. It can also be seen on the hike to the top of Mt. Bartle Frere.
