    Inflorescences
    Inflorescence a panicle; embraced at base by subtending leaf. Panicle open; ovate; 4-13 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; cuspidate; 2-2.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; cuspidate; 2-2.5 mm long; falling entire.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.5 length of spikelet; membranous; without keels; 5-7 -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 barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 9 -veined; pilose; acute. Fertile lemma oblong; dorsally compressed; 1.5 mm long; indurate; dark brown; shiny; without keel. Lemma margins involute. Lemma apex obtuse. Palea involute; indurate.

    Leaf lamina
    Leaf laminae 5–15 cm. long and 5–15 mm. wide, linear or linear-lanceolate, acute.
    Inflorescences
    Panicle 4–13 cm. long, ovate, moderately to much branched, usually scarcely exserted from the uppermost leaf-sheath.
    Spikelets
    Spikelets 2–2.5 mm. long, ovate, glabrous, apiculate; inferior glume 1/2 the length of the spikelet, broadly ovate, 5–7-nerved; superior glume as long as the spikelet, 9-nerved; inferior lemma similar to the superior glume, sterile, its palea poorly developed; superior lemma and palea dark, glossy.
