Robert Powell: Tree Pictures, South-Western Australia

Rottnest cypress (Callitris preissii)
Rottnest cypress stands out as one of the very few conifers native to the Perth area, and particularly for the rich colour of its foliage, varying from a strong green in some individuals to bluish-green in others.

In the Perth area Rottnest cypress is limited to Rottnest and Garden Islands, a few spots along the coast, and some limestone slopes bordering the lower Swan Estuary — the pictures show how remarkably different in form these Estuary specimens are from all the rest.
