    Inflorescences
    Inflorescence a panicle, or composed of racemes (1). Panicle contracted. Racemes single (1/1); oblong (1/1); unilateral (1/1). Rhachis angular (1/1). Spikelet packing broadside to rhachis (1/1); crowded (1/1). Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-4 fertile florets (1), or 6-8 fertile florets (1); with diminished florets at the apex. Spikelets linear (1), or oblong (1); laterally compressed; 5-8-11 mm long; breaking up at maturity; disarticulating between fertile florets but the lowest falling with glumes attached. Rhachilla internodes elongated between glumes.
    Fertile
    Spikelets comprising 3-4 fertile florets (1), or 6-8 fertile florets (1); with diminished florets at the apex. Spikelets linear (1), or oblong (1); laterally compressed; 5-8-11 mm long; breaking up at maturity; disarticulating between fertile florets but the lowest falling with glumes attached. Rhachilla internodes elongated between glumes.
    Glume
    Glumes deciduous with pedicel attached; shorter than spikelet; thinner than fertile lemma. Lower glume oblong; 0.5 length of upper glume; herbaceous; 1-keeled; 3 -veined. Lower glume lateral veins ribbed. Lower glume apex obtuse. Upper glume oblong; 0.8-0.9-1 length of adjacent fertile lemma; herbaceous; with undifferentiated margins (1), or membranous margins (1); 1-keeled; 5-6 -veined (1), or 7 -veined. Upper glume lateral veins ribbed. Upper glume apex obtuse (1), or acute (1).
    Florets
    Fertile lemma oblong; coriaceous; of similar consistency on margins (1), or much thinner on margins (1); keeled; 5-7 -veined. Lemma midvein without distinctive roughness, or scaberulous (1). Lemma lateral veins ribbed. Lemma apex obtuse. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
    Fruits
    Caryopsis with adherent pericarp; fusiform (1/1); dorsally compressed (1/1); concavo-convex (1/1); apex rostrate. Hilum punctiform.
