Leaf sheaths pubescent; auricles usually conspicuous; blade lanceolate or ovate-elliptical, variable in size, transverse veins scarcely visible. Inflorescence fully bracteate, iterauctant, initially densely glomerate with many pseudospikelets, terminal to a leafy shoot, later spicate, lateral to leafless flowering branches, subtended by several large bracts. Spikelets 1-flowered, with a rachilla extension. Glumes 2 or 3, long mucronate or awned; lemma similar to glumes, convolute. Palea thin, 2-keeled. Lodicules 3. Stamens 6; filaments free.
