The first species we found was Cycas media (below). One site was easy to collect plants from and the other wasn't. Can you guess which was the painful one? Yes, the one on the right with the tall spiky grass, loose rocks, holes in the ground, and a steep hill!

This was the only population of Cycas terryana we found. The species was described by Dr Paul Forster (Queensland herbarium) and named after the cycad biologist Dr Irene Terry (University of Utah).
The third species was Cycas ophiolitica. As for all members of Cycas, the seeds are in a loose "cone" (bottom left), and there is a separate pollen cone (bottom right).
There were fewer sites than I expected -- land has been cleared for agriculture and plants stolen from the wild. Unfortunately, cycads are the world's most endangered plants and searching unsuccessfully for these plants reinforced this sad reality.
