On upper bank of Wallagaraugh River among rocks, resprouting after fire 13 months ago. It keyed to L. muelleri pretty well. I see the culms are a little bit finely tuberculate, which could make it L. verruculosa. This species has not made it into the keys in PlantNet yet, so I'm not sure what the distinguishing feature is apart from the tuberculate culms, but having checked images of that species on PlantNet, I don't think this is a good match. L. verruculosa seems to have denser inflorescences.
