I have just looked at both the VicFlora and NSW PlantNet keys and descriptions and both include November in the Flowering period (PlantNet suggests flowering as late as December). Additionally the PlantNet key splits D. dendrobioides from D. punctata based on the "Petal claw gradually expanded into the lamina" (D. dendrobioides) vs. "Petal lamina suddenly expanded at the apex of the claw" (D. punctata). (The claw refers to the petal 'stalk' and lamina refers to the big 'round parts' of the petal; tennis racket vs. badminton racket). Looking at this plant and comparing it to images of both species I feel this is a better fit for D. punctata. Here are some sightings for reference: D. dendrobioides Diuris dendrobioides (Late Mauve Doubletail) D. punctata Diuris punctata (Purple Donkey Orchid)
