Morphology General Habit
Perennial; caespitose. Culms erect; robust; 150-400 cm long. Leaf-sheaths keeled. Ligule a ciliolate membrane. Leaf-blades 30-100 cm long; 5-25 mm wide. Leaf-blade midrib conspicuous. Leaf-blade surface scaberulous; rough abaxially. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 30-40 cm long. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; 1-1.2 cm long; scarious. Racemes 1; single; cuneate; bearing a triad of spikelets; bearing 1 fertile spikelets on each. Rhachis fragile at the nodes. Spikelets in threes (basal paired). Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 2 in the cluster. Pedicels oblong; 0.5 mm long; tip oblique.
Sterile
Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; lanceolate; 7-9 mm long; equalling fertile. Basal sterile spikelet glumes scaberulous; glabrous; lower glume muticous. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 7-9 mm long; as long as fertile; separately deciduous. Companion sterile spikelet callus linear; 2 mm long; truncate. Companion sterile spikelet glumes chartaceous; acuminate. Companion sterile spikelet lemmas 2; enclosed by glumes.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 7-9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus linear; 2-3 mm long; pilose; base pungent; attached obliquely. Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; lanceolate; 7-9 mm long; equalling fertile. Basal sterile spikelet glumes scaberulous; glabrous; lower glume muticous. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 7-9 mm long; as long as fertile; separately deciduous. Companion sterile spikelet callus linear; 2 mm long; truncate. Companion sterile spikelet glumes chartaceous; acuminate. Companion sterile spikelet lemmas 2; enclosed by glumes.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 7-9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus linear; 2-3 mm long; pilose; base pungent; attached obliquely.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels. Lower glume surface puberulous. Upper glume oblong; coriaceous; 3 -veined.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 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 hispidulous. Palea absent or minute.
