Morphology General Habit
Perennial; caespitose. Rhizomes short. Butt sheaths persistent and investing base of culm; with compacted dead sheaths. Culms erect; 30-60 cm long. Culm-internodes distally pubescent. Leaf-sheaths pilose; with reflexed hairs. Ligule an eciliate membrane; 1-1.6 mm long; lacerate. Leaf-blades flat; 10-20 cm long; 3-5 mm wide. Leaf-blade venation distinct. Leaf-blade surface pilose; densely hairy; hairy on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate; 10 cm long; bearing few spikelets. Primary panicle branches 1-2 -nate; bearing 1 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 4-4.5 mm long; scaberulous; glabrous.
Fertile
Spikelets comprising 6-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 4-4.5 mm long; scaberulous; glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 13-19 mm long; 1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 13-19 mm long; 0.66-1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic, or oblong; 20 mm long; chartaceous; much thinner on margins; without keel; 5 -veined. Lemma midvein scaberulous. Lemma surface asperulous; rough on veins. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn subapical; straight, or curved; 10-12 mm long overall. Palea 15 mm long. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
