Primary panicle branches simple, or moderately divided; 3-12 cm long; naked below, or bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-5.5 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; compressed slightly; 3-4 mm long; falling entire. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation slender (obscure).
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; compressed slightly; 3-4 mm long; falling entire. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation slender (obscure).
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume orbicular; 0.33 length of spikelet; membranous; 1-keeled; 3-5 -veined. Lower glume apex cuspidate. Upper glume ovate; 3-4 mm long; 1 length of spikelet; membranous; without keels; keel-less except near apex; 5-7 -veined. Upper glume lateral veins ribbed. Upper glume apex laterally pinched.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; scarious; 5 -veined; sulcate; acute. Palea of lower sterile floret winged on keels. Fertile lemma orbicular; dorsally compressed; gibbous; 2.5-3 mm long; indurate; shiny; without keel; 3 -veined. Lemma surface rugose. Lemma margins involute. Lemma apex acute. Palea indurate.
