Morphology General Habit
Annual. Culms rambling; weak; 30-80 cm long; rooting from lower nodes. Culm-nodes glabrous, or bearded. Ligule an eciliate membrane; acute. Leaf-blades involute, or convolute; 2-5 cm long; 4-6 mm wide. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle with branches tipped by a raceme. Panicle open; oblong; 3-10 cm long. Panicle branches capillary. Racemes bearing few fertile spikelets, or many spikelets; 1-3 fertile spikelets on each. Rhachis evident, or obsolete; fragile at the nodes; subterete; ciliate on margins. Rhachis internodes linear; 1-2 mm long. Spikelets in pairs, or in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster, or 2 in the cluster. Pedicels linear; 1-2 mm long; with a translucent median line (also present in internodes); ciliate.
Sterile
Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; shorter than fertile; separately deciduous. Companion sterile spikelet lemmas enclosed by glumes.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; 2-3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely. Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; shorter than fertile; separately deciduous. Companion sterile spikelet lemmas enclosed by glumes.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; 2-3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 1 length of spikelet; chartaceous; 2-keeled; keeled obtusely; 7 -veined. Lower glume surface concave; glabrous, or villous. Upper glume lanceolate, or oblong; chartaceous; with hyaline margins; 1-keeled; 3-5 -veined.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 1-1.5 mm long; hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma linear; 1-2 mm long; hyaline; without keel; 1 -veined. Lemma apex entire; acute; awned; 1 -awned. Principal lemma awn geniculate; 10-12 mm long overall; with twisted column. Column of lemma awn 5 mm long; glabrous. Palea absent or minute.
Morphology Reproductive morphology Flowers
Anthers 3; 1-1.5 mm long.
Distribution
Asia-tropical: India.
