I know I keep banging on here, but I really do think we have this species here. I've been through two guidebooks as well as VicFlora (PlantNet doesn't seem to have a key for this species), and absolutely everything is matching up on the plants that I've indicated as this species. It is commonly mis-labelled. Have a look at VicFlora specifically, as you'll see the measurements there are actually pretty bang on. I've also had a look through the meagre records here, specifically those by Tobias, and my plants definitely seem the same. Thoughts welcomed as always. Here is hoping!
