that's a good starting list prier
We've got Pterocaulon sp. growing on our property, can't remember the species offhand, smells like apples.
Add Barringtonia acutangula too, this is the one being researched currently for painkilling properties.
Add Stictocardia tiliifolia too in convolvulaceae, QLD Woodrose.
Add Trichodesma zelanyicum (sp.) Camel Bush.
We;ve got plenty of Evolvus alsinoides here too, pituri substitute (one variety).
I've also found some Tribulus micrococca growing locally and am propagating, a friend has reported effects from northern species.
