It is strange missing York Peninsula! It could be data deficient, or maybe there's too dense rain forest there? It says on Wiki about half the area is used for cattle grazing, I wonder if the leaves are edible so doesn't get a chance to grow.

I'm finding plenty about the medicinal properties of O. turpethum leaves so it could be palatable.

I had a really nice propery eyed up in the rain forest there last winter when we had weeks of exceptionally cold freezing weather!
