Spikelets of corresponding inflorescences relatively similar or markedly dissimilar; terminal spikelets chasmogamous or uncommonly mixed with cleistogamous spikelets; Type 2 spikelets cleistogamous. Spikelets slightly dorsi-ventrally compressed; lower glume absent or vestigial, upper glume and lower lemma, chartaceous, usually as long as the spikelet; lower floret barren without a palea; upper lemma chartaceous to cartilaginous, slightly hardened, papery texture, loosely overlapping the caryopsis.
