    Inflorescences
    Inflorescence composed of racemes; exserted (3), or embraced at base by subtending leaf (1). Racemes single; unilateral (1), or bilateral (3). Rhachis fragile at the nodes; flattened (3), or angular (1). Spikelet packing broadside to rhachis; 2 -rowed (1/1). Rhachis internodes linear (3), or clavate (1); falling with spikelet above. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets (3), or 6 fertile florets (2), or 7-8 fertile florets (1); with diminished florets at the apex. Spikelets lanceolate (1), or cuneate (3); laterally compressed; 6-11-20 mm long; falling entire; deciduous with accessory branch structures. Rhachilla internodes glabrous (3), or sparsely hairy (1).
    Fertile
    Spikelets comprising 3-5 fertile florets (3), or 6 fertile florets (2), or 7-8 fertile florets (1); with diminished florets at the apex. Spikelets lanceolate (1), or cuneate (3); laterally compressed; 6-11-20 mm long; falling entire; deciduous with accessory branch structures. Rhachilla internodes glabrous (3), or sparsely hairy (1).
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate (3), or oblong (1); 0.5-0.6325-0.9 length of upper glume; chartaceous (1), or herbaceous (3); without keels (1), or 1-keeled (3); 3 -veined (3), or 5-7 -veined (1). Lower glume lateral veins without ribs (3), or ribbed (1). Lower glume surface smooth (3), or scabrous (2); glabrous (3), or pubescent (1), or villous (2). Lower glume apex obtuse (1), or acute (3). Upper glume oblong, or obovate (1); 0.8-1.037-1.2 length of adjacent fertile lemma; chartaceous (1), or herbaceous (3); with undifferentiated margins (3), or membranous margins (1); without keels (1), or 1-keeled (3); 5-6 -veined (3), or 7 -veined, or 8-11 -veined (1). Upper glume lateral veins ribbed. Upper glume surface smooth (3), or scabrous (2); glabrous (3), or pubescent (1), or villous (2). Upper glume apex emarginate (1), or obtuse (2), or acute (2).
    Florets
    Fertile lemma lanceolate (3), or oblong (1); cartilaginous (1), or coriaceous (3); of similar consistency on margins (1), or much thinner on margins (3); without keel (1), or keeled (3); 5 -veined (1), or 7-9 -veined (3). Lemma lateral veins obscure (3/3). Lemma surface glabrous, or villous (1). Lemma apex acute (2), or acuminate (2); muticous (1), or awned (3); 1 -awned (3/3). Principal lemma awn dorsal (3/3); straight (1/3), or curved (1/3), or geniculate (2/3). Palea 0.9-0.925-1 length of lemma; 2 -veined. Palea keels smooth (3), or scaberulous (1); eciliate (2), or ciliolate (1), or ciliate (1). Apical sterile florets resembling fertile though underdeveloped.
