INFLORESCENCE Inflorescence a panicle.

Panicle open.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 1.3–2.325–3.8 mm long; breaking up at maturity; disarticulating below each fertile floret.

Upper glume elliptic, or oblong (1); 0.9–0.95–1 length of adjacent fertile lemma; membranous; without keels; 3 -veined (1/1). Upper glume apex obtuse (1), or acute.

FLORETS Fertile lemma ovate; membranous; without keel; wingless; 3 -veined. Lemma midvein ciliate (1), or pubescent (1). Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex emarginate (1), or obtuse; muticous, or mucronate (1). Palea 1 length of lemma; 2 -veined. Palea keels eciliate (1), or pubescent (1). Palea surface pubescent (1), or pilose (1).
