    Inflorescences
    Inflorescence of 3–14 widely spaced racemes, these 1–7 cm. long, slender, secund, spreading horizontally or deflexing at maturity, bearing mostly paired spikelets on a triquetrous rhachis.
    Spikelets
    Spikelets 2–3.5 mm. long, glabrous, subacute.

Upper glume oblong; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma elliptic; 2-2.5 mm long; indurate; without keel. Lemma surface corrugate. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.
