Spikelets appressed to the rachis, with 1-2 florets. Glumes displaced so that they lie adjacent to each other and cover the florets, 6-12 mm long, not keeled. blunt, unawned. Lemmas nearly as long as the glumes, not keeled, unawned.

Caryopsis not adhering to the lemma and palea, but enclosed by the glumes and rachis.
