Sorry if I missed it above but isn't there a plant or tree in Australia whose seeds only open in the heat of a fire? They require fire to germinate. I have seen films of it but can't recall the name.

Nice that we can be having these discussions rather than trying to find out who is where and still has a house.
Rowan, your knowledge of the area is astounding. Have you written a book? And if that is above and I missed it, I apologize once again.
