It should be labeled as a location plant.
Could this be a case of there are no Ceph at Emu Point today but 30 years ago there where?
Wild Cephalotus population in Emu Point doesn't grow. Same story is with so called Cephalotus Walpole - in this location there also aren't and they have never grown there. The correct location is Coal Mine Beach.... both locations Emu Point and Walpole were given with purpose from Allen Lowrie and Phill Mann to protect the real locations from poachers of the wild growing Cephalotus...
So, Fred is quite right in his arguments.

(it helps if you visit "moribund" sites) were aware that our Australian cousins were giving false location names to Cephalotus. They no doubt have a list of what came from where but it does make a bit of a mockery of the location name usage. It does keep the poachers busy looking in the wrong places though. I must admit I thought it would have been much better to use an alpha numeric location identification to lessen confusion.
