    Habit
    Perennial. Rhizomes short; knotty. Butt sheaths pubescent. Culms erect, or geniculately ascending; (15-)40-75 cm long. Lateral branches lacking. Ligule a ciliate membrane. Leaf-blade base cordate, or amplexicaul. Leaf-blades lanceolate; 4-11.5 cm long; 5-16 mm wide. Leaf-blade surface scabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; oblong; 3-10 cm long. Primary panicle branches simple; bearing spikelets almost to the base. Panicle branches pilose; with clavellate hairs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 3-15 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; obtuse; 2.5-5.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; obtuse; 2.5-5.5 mm long; falling entire.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.33-0.5 length of spikelet; membranous; without keels; 7 -veined. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 9 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 9 -veined; acute. Palea of lower sterile floret pilose. Fertile lemma oblong; dorsally compressed; 3.5-5.5 mm long; indurate; pallid; without keel. Lemma margins involute. Lemma apex obtuse; pubescent. Palea involute; indurate.
