Leaf-blades lanceolate; 1-2 cm long; 2-2.5 mm wide. Leaf-blade surface pilose; with tubercle-based hairs.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; oblong; 0.6-0.7 cm long; bearing few fertile spikelets; bearing 1 fertile spikelets on each. Rhachis obsolete (raceme capitate).

    Spikelets
    Companion sterile spikelets well-developed; male; oblong; dorsally compressed; 4.5-6.5 mm long; longer than fertile; persistent.

Lower glume lanceolate; 4.5-5.5 mm long; 1.2 length of upper glume; 1 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex obtuse, or acute. Upper glume lanceolate; 3.5-5 mm long; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 3 mm long; hyaline. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn geniculate; 30-45 mm long overall; with twisted column. Column of lemma awn 10-25 mm long; pubescent. Palea absent or minute.
