Distribution

Asia-Tropical: New Guinea present, Australasia: Tasmania (Tasmania present); Victoria (Victoria present), Mt Kosciusko present, New Zealand present, Papua New Guinea present, SE. Australia present, Upper Hume R present, West Irian present, summit of Mt Wilhelmina present
New Zealand, Tasmania, SE. Australia (Victoria, Upper Hume R. and Mt Kosciusko, according to Bentham, l.c.; no specimens seen); in Malesia: New Guinea (West Irian, summit of Mt Wilhelmina; Papua New Guinea).

Notes

Whether the glumes are persistent or caducous can often only be seen in old inflorescences. It is not impossible that hybrids occur with U. compacta, thus giving more variability and plants in which the glumes fall very late. In these plants the sharply triquetrous culms become more or less rounded and smooth instead of scabrous (not found in Malesia).
