    [GB]
    Habit
    Annual; mat forming. Culms geniculately ascending, or decumbent; 30-80 cm long; wiry; rooting from lower nodes. Lateral branches sparse. Leaf-sheaths as wide as blade at the collar; glabrous on surface. Ligule an eciliate membrane. Leaf-blades 15-30 cm long; 3-5 mm wide; flaccid. Leaf-blade venation distinct. Leaf-blade surface pilose; with tubercle-based hairs. Leaf-blade margins glabrous, or ciliate.
    Inflorescences
    Synflorescence compound; fasciculate; 20-30 cm long. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; 0.7-1 cm long; membranous; tuberculate; setose. Racemes 1; single; 0.6-0.8 cm long; bearing few fertile spikelets; bearing 2 fertile spikelets on each. Rhachis fragile at the nodes. Rhachis internodes linear. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear.
    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 4-5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus oblong; 0.5 mm long; truncate. Companion sterile spikelet glumes cartilaginous; tuberculate; ciliate on margins; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; attached obliquely.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 4-5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus oblong; 0.5 mm long; truncate. Companion sterile spikelet glumes cartilaginous; tuberculate; ciliate on margins; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 3-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; attached obliquely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; cartilaginous; without keels. Lower glume surface hispidulous. Upper glume oblong; 1-keeled.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 1 mm long; hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma oblong. Lemma apex entire; awned; 1 -awned. Principal lemma awn geniculate; 18-24 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
