Morphology General Habit
Annual; caespitose. Culms 60-90 cm long; without nodal roots, or rooting from lower nodes. Leaf-sheaths glabrous on surface. Ligule a ciliate membrane. Leaf-blades 7-12 cm long; 3 mm wide. Leaf-blade surface scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 4-12; digitate; erect, or ascending; unilateral; 4-8 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; regular. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.7-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.
Fertile
Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 3.7-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume lanceolate; 1.5-2.5 mm long; 0.5-0.6 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.5-5 mm long; 0.66-0.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute; mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate, or elliptic; laterally compressed; 3.7-6 mm long; cartilaginous; keeled; 3 -veined. Lemma surface scabrous. Lemma margins ciliate; hairy all along, or above. Lemma hairs 1-2 mm long. Lemma apex lobed; 2 -fid; incised 0.33 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; 7-16 mm long overall. Lateral lemma awns arising on apex of lobes; 3-7 mm long; shorter than principal. Apical sterile florets 1 in number; barren; oblong; 1.3-4 mm long. Apical sterile lemmas lobed; 2 -fid; awned; 3 -awned. Apical sterile lemma awns 1-15 mm long; 3 per spikelet in number.
