Tetrarrhena juncea

Tetrarrhena juncea is a wiry, tufted perennial grass of the Poaceae family, forming dense clumps with long, slender, scrambling to weakly climbing culms 0.5 to 2 metres long that may lean on surrounding shrubs for support. The stems are smooth, glabrous, and rather rigid, becoming somewhat woody at the base, and bear short, narrow, distichous leaves along their length. The leaf blades are linear, 1 to 5 centimetres long and 1 to 3 millimetres wide, flat or inrolled, with a stiff, harsh texture and finely scabrid margins; the sheaths are smooth and the ligule is a very short membrane. The inflorescence is a narrow, slender, spike-like raceme 3 to 10 centimetres long, bearing few, well-spaced, single-flowered spikelets 4 to 6 millimetres long with persistent glumes; the floret bears a short awn. Native to southeastern Australia, including Victoria, Tasmania, New South Wales and South Australia, the grass is a dominant element of the understorey in damp sclerophyll forest and wet heath.
