Indeed I did first. Couldn't confirm anything however...

Hi Team, Was walking in the wetlands boardwalk at Glenorchy a fortnight ago. Saw this interesting looking plant growing both submersed and emersed. Air temp was in the low single digits, no idea how cold the water was, but nothing else green was really growing below the surface. Plenty of other swamp plants and bits of other submerged stuff growing, unfortunately didimo was quite prevalent in some areas. Anyway, does anybody know what this plant was? I'd almost say it was hygrophila.
