    [GB]
    Habit
    Annual; caespitose. Culms erect; 20-45 cm long. Culm-nodes bearded. Lateral branches lacking, or sparse. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule an eciliate membrane. Leaf-blades linear, or lanceolate; 6-12 cm long; 5-12 mm wide. Leaf-blade surface pilose; with tubercle-based hairs.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1-4; single, or paired, or digitate; 3-5 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis internodes linear. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; without a translucent median line; ciliate.
    Spikelets
    Basal sterile spikelets well-developed; 6-8 in number; barren, or male; elliptic, or oblong; 3.5-4.5 mm long. Basal sterile spikelet glumes winged on keel; tuberculate on margins and ciliate on margins. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 4-5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes tuberculate on margins; ciliate on margins. Companion sterile spikelet lemmas enclosed by glumes; muticous. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; obtuse; 3.5-4.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely.
    Sterile
    Basal sterile spikelets well-developed; 6-8 in number; barren, or male; elliptic, or oblong; 3.5-4.5 mm long. Basal sterile spikelet glumes winged on keel; tuberculate on margins and ciliate on margins. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 4-5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes tuberculate on margins; ciliate on margins. Companion sterile spikelet lemmas enclosed by glumes; muticous.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; obtuse; 3.5-4.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels. Lower glume surface tuberculate (along fringe); with a transverse fringe of hair. Upper glume lanceolate; 1-keeled; 3 -veined.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret hyaline. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 25-30 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
