I reported this as Hardenbergia violacea but there has been an undocumented change to unverified climber. This means I can’t verify it until I once again say it is hardenbergia.
I can see the glands on the rib between the pinnules in the leaf in side view. Difficult to tell apart from A. mearnsii. Look at the first pic at Acacia mearnsii showing the dark colour of the branchlets for A. mearnsii. A. parramattensis does not have that colour, I think.
I'm sorry, but I didn't realize it had changed. I thought it was still Cyanicula? Could you provide me with a source? I don't receive papers to notify me of any name changes and only have the Australian Plant Census to go off, and that appears to list Cyanicula as the currently accepted name.
