Morphology General Habit
Annual. Culms decumbent; 6-30 cm long. Ligule an eciliate membrane. Leaf-blades 1-5 cm long; 2-3 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 2; paired; erect; 1-2.5 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis hairs dark brown. Rhachis internodes linear. Spikelets appressed; in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels adnate at the base to lower glume of sessile spikelet; linear; 2 mm long; ciliate (brown hairs).
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets well-developed; 2-3 in number; barren; larger than fertile. Basal sterile spikelet lemmas awnless. Companion sterile spikelets represented by barren pedicels. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; truncate; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely. Spikelet callus hairs dark brown.
Sterile
Basal sterile spikelets well-developed; 2-3 in number; barren; larger than fertile. Basal sterile spikelet lemmas awnless. Companion sterile spikelets represented by barren pedicels.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; truncate; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely. Spikelet callus hairs dark brown.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; reaching apex of florets; firmer than fertile lemma. Lower glume cuneate; 1 length of spikelet; chartaceous to coriaceous; much thinner above; dark brown; without keels; 7 -veined. Lower glume primary vein falling short of apex. Lower glume lateral veins all falling short of apex. Lower glume surface glabrous, or pilose. Lower glume apex emarginate, or truncate. Upper glume chartaceous.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male; with palea. Lemma of lower sterile floret oblong; 1 length of spikelet; hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma linear; 2 mm long; hyaline; without keel; 1 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 10-20 mm long overall; with twisted column. Column of lemma awn hispidulous. Palea hyaline; 0 -veined; without keels.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 2.
Distribution
Asia-tropical: India.
