Once upon a time, not all that many years ago, I spent most weekends down a rainforest gulley somewhere on the south coast. That passion petered out, as passions do, and was replaced by beach walking.

However, the Dorrigo rainforest challenged my faithlessness and enticed me into its sun dappled gloom for a pleasant stroll, as I reacquainted myself with ferns, fungi, and the circles and lines of lichen. I was startled by the profusion of unexpectedly bright red berries on the walking stick palm (Linospadix monostachya): I'm used to rainforest's multiplicity of greens and browns.
