Spikelets 1(–2)-flowered, sunk in recesses along rachis; glumes 1 (in all but the terminal spikelet which has 2), enclosing the recesses except at anthesis, strongly veined, firm; lemma membranous, shorter than glume, inserted against the rachis (i.e. palea between lemma and glume), 3-nerved, the lateral nerves short.
A monotypic genus, occurring naturally on saline or gypseous soils from southern Europe to the Middle East.
