Weakly tufted, usually short-lived perennials. Leaf-blades flat; ligules membranous, rather coarse-textured and usually prominently nerved. Culms usually tall, up to 8-noded. Inflorescence an open, broadly pyramidal panicle. Spikelets bisexual, long-pedicellate, laterally compressed, 3–6-flowered, breaking up above the glumes and between the florets; glumes 2, the lower 3-nerved (the lateral pair sometimes indistinct), the upper 3-, or 5-nerved; lemma entire or shorlty 2-lobed, firmer than glumes, 5-(rarely 7-)nerved, weakly keeled, the lower lemma in spikelet sometimes shortly awned; palea acute, about as long as lemma.
Monotypic genus endemic in south-eastern Australia.
