The leaves are parallel veined, scabrous margined, keeled.
The zygomorphic flowers are arranged in a terminal panicle made of congested racemes of spikelets. At the base of each spikelet are 2 structures called glumes. The first glume small and the second larger and pubescent. In each ovate spikelet there are flowering structures each is subtended by 2 additional structures (lemma and palea) and are pubescent. There are 3-5 florets with 3 stamens and a superior ovary each with a single locule and seed. The fruit is a caryopsis.
