Sorry for the title.
The helicopter tree (Gyrocarpus americanus) is a common species on limestone at Chillagoe. Most individuals had lost their leaves, but still managed to look windswept and interesting with their golden bark.
No, really. The bark is a lot more attractive than it appears in this picture. Think of it as Gyrocarpus's passport photo.
Two species of kurrajong are abundant here. This is the Chillagoe kurrajong (Brachychiton chillagoensis), which is also found in the Undara region. I produced a more detailed post about this and the widespread Brachychiton australis during my last trip to Chillagoe.
The dark bark of Brachychiton chillagoensis sets off the pale leaves.
There's more karst to come ...
