At Mount Annan one of the trails we followed was the Wollemi Walk. An emergent rainforest tree that dates back around 150 million years, Wollemi nobilis was only discovered by accident in 1994 in the Blue Mountains (west of Sydney), where they grow on wet ledges in a deep, sheltered gorge. There are less than 50 in the wild and some may be between 500 and 1000 years old.
Apart from their importance in terms of diversity, these pines have already been found to contain taxol, used in cancer treatment. How many more plants might be out there still to reveal their curative properties?
Coexistent with the dinosaurs, the Wollemi Pine was only previously known as a fossil.
The original tree is in the Botanic Gardens in Sydney.
