I came across this website when searching for information on Phaius australis. You may have already looked at this website, but in point 2. it differentiates the differences between australis and tankervilleae. Is this how you tell the difference when you come across a plant masquerading as australis? I am really interested to know cos I want to keep my eyes open in the future.
Also the website for Yalta orchids who are selling australis - go to - Australian Native Species, then go to - stock list and australis will come up as the last entry on this page.
