    Inflorescences
    Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole. Spatheole linear. Racemes 2; paired; 3-6 cm long; bearing 5-10 fertile spikelets on each. Rhachis fragile at the nodes; ciliate on margins. Rhachis hairs 3 mm long. Rhachis internodes linear; 5-6 mm long. Rhachis internode tip transverse; cupuliform; with simple rim. Spikelets in pairs.

    Sterile
    Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; linear; 2.5-6 mm long; shorter than fertile. Companion sterile spikelet glumes chartaceous; acute.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 8-12 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted. Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; linear; 2.5-6 mm long; shorter than fertile. Companion sterile spikelet glumes chartaceous; acute.
    Fertile

    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; coriaceous; 2-keeled; keeled laterally. Lower glume intercarinal veins absent. Lower glume surface concave. Upper glume linear; membranous; 1-keeled. Upper glume muticous.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 2 -veined. Fertile lemma lanceolate; hyaline; without keel. Lemma margins ciliate. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 17-18 mm long overall; with twisted column. Column of lemma awn glabrous.
