Stems and leaves of Bare Twig-rush
Photo: A J Brown
Australian, New Zealand and New Caledonian native.
Slender perennial sedge with a long rhizome. Stems are rigid and circular in cross-section and leaf blades are reduced to short, erect, flattened points. Leaf sheaths are straw-coloured to pale or dull reddish or grey-brown. Flower-heads are narrow, erect panicles from 1-8 cm long and 1 cm wide. The lowest flower bract is shorter than the flower-head.
Spikelets are few, 3-6 mm long and one flowered. The 4-5 glumes are red-brown to grey-brown. Fruit is a near-globular, shining black to to dark red-brown nut.
Growing in brackish swamps and near-coastal saltmarsh.
Most of the Victorian species of Twig-rush grow in fresh-water habitats.
