    Habit
    Annual. Culms erect (5/5), or geniculately ascending (2/5); slender (2/2); 7-23.03-55 cm long. Ligule an eciliate membrane.
    Inflorescences
    Inflorescence a panicle (6), or composed of racemes (2); exserted (7), or embraced at base by subtending leaf (1). Panicle open (6/6). Racemes linear (2/2), or lanceolate (2/2); paucilateral (2/2). Spikelets solitary. Fertile spikelets pedicelled. Pedicels cuneate.
    Spikelets
    Spikelets comprising 2 fertile florets (2), or 3 fertile florets (5), or 4 fertile florets (4), or 5-7 fertile florets (2), or 8 fertile florets (1); with a barren rhachilla extension (2), or with diminished florets at the apex (6). Spikelets lanceolate (2), or oblong (5), or cuneate (1); laterally compressed; 4.5-10.5-19 mm long; breaking up at maturity; disarticulating between fertile florets but the lowest falling with glumes attached. Rhachilla internodes glabrous (7), or pubescent (1). Floret callus evident; pubescent (5/5).
    Fertile
    Spikelets comprising 2 fertile florets (2), or 3 fertile florets (5), or 4 fertile florets (4), or 5-7 fertile florets (2), or 8 fertile florets (1); with a barren rhachilla extension (2), or with diminished florets at the apex (6). Spikelets lanceolate (2), or oblong (5), or cuneate (1); laterally compressed; 4.5-10.5-19 mm long; breaking up at maturity; disarticulating between fertile florets but the lowest falling with glumes attached. Rhachilla internodes glabrous (7), or pubescent (1). Floret callus evident; pubescent (5/5).
    Glume
    Glumes deciduous with pedicel attached; shorter than spikelet (7), or reaching apex of florets (1); thinner than fertile lemma. Lower glume lanceolate (7), or elliptic (1); 0.5-0.6475-0.9 length of upper glume; membranous; 1-keeled; 1 -veined (1), or 3 -veined (6), or 7 -veined (1). Lower glume lateral veins absent (1), or distinct (7); without ribs (6/7), or ribbed (1/7). Lower glume apex acute (4), or acuminate (4). Upper glume lanceolate (7), or elliptic (1); 0.7-1.037-1.8 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined (4), or 4 -veined (1), or 5 -veined (4), or 6-7 -veined (1), or 9 -veined (1). Upper glume lateral veins without ribs (7), or ribbed (1). Upper glume apex acute (4), or acuminate (4).
    Florets
    Fertile lemma lanceolate (2), or elliptic (2), or oblong (4); chartaceous (7), or coriaceous (1); without keel; 5 -veined. Lemma surface smooth (7), or scaberulous (1); glabrous (5), or puberulous (1), or pubescent (2). Lemma apex entire (2), or dentate (4), or lobed (2); 2 -fid (6/6); incised 0.1 of lemma length; acute (3/3); muticous (1), or awned (7); 1 -awned (3/7), or 3 -awned (4/7). Principal lemma awn dorsal (7/7); geniculate (7/7). Lateral lemma awns shorter than principal (4/4). Palea 0.6-0.775-0.9 length of lemma. Palea keels smooth (7), or scabrous (1); eciliate (5), or ciliolate (2), or ciliate (1). Apical sterile florets resembling fertile though underdeveloped (6/6).
