Spikelets in homogamous, homomorphic, sessile-pedicellate pairs, with 1 or 2 florets. Lower glumes herbaceous to cartilaginous, longitudinally grooved, margins inflexed, 4-6-veined, usually keeled; upper glumes 3-veined, mucronate or shortly awned; lower florets absent, or reduced and sterile; upper florets bisexual; upper lemmas usually awned; anthers (2) 3. x = 10.
