INFLORESCENCE Inflorescence composed of racemes; with 1–2 peduncles per sheath.

Racemes 1; single; arcuate; unilateral; 5–9 cm long. Rhachis 1 mm wide. Spikelet packing crowded.

GLUMES Glumes one to two the lower present in some spikelets; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.4 mm long; 0.2 length of spikelet. Upper glume elliptic; 1–1.5 mm long; 0.33–0.66 length of spikelet; membranous; without keels.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous. Fertile lemma elliptic; 2–2.3 mm long; indurate; pallid; without keel. Lemma surface striate. Lemma margins involute. Palea involute; indurate.
