Spikelets very compressed laterally, with 1 single hermaphroditic flower, articulated above or below the glumes. Glumes subequal, shorter than the flower, uninervated. Lemma membranous, uninervated, mutic. Palea with 1-2 inconspicuous veins, rounded or with 1 keel. Lodicules generally absent. Androecium with 2 or 3 stamens. Obovoid or oblongoid caryopsis, with embryo almost the same length; pericarp not welded to the seed. Rounded thread.

- Etymology

- Cytology
The basic chromosome number of the genus is x = 8 and 9, with somatic chromosome numbers of 2n = 16, 18, 32, 36 and 54, since there are diploid species and a polyploid series. Relatively "small" chromosomes.
