Morphology General Habit
Perennial; caespitose. Basal innovations extravaginal. Culms erect, or geniculately ascending; 45-90 cm long; 3 -noded. Culm-nodes pubescent. Lateral branches lacking. Leaf-sheaths puberulous to pilose; with tubercle-based hairs. Ligule an eciliate membrane; 0.9-2 mm long; truncate, or acute. Leaf-blades 20-27 cm long; 4-7 mm wide; flaccid. Leaf-blade surface scabrous; rough on both sides; glabrous to pilose; hairy adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle pubescent above. Panicle open; nodding; 16-17 cm long; 3-3.5 cm wide. Primary panicle branches 2 -nate; 4-8.5 cm long; bearing 2-4 fertile spikelets on each lower branch. Panicle axis smooth, or scaberulous. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets with diminished florets at the apex. Spikelets laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.75-2.85 mm long; pubescent. Floret callus pilose; disarticulating obliquely; with circular scar.
Fertile
Spikelets with diminished florets at the apex. Spikelets laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.75-2.85 mm long; pubescent. Floret callus pilose; disarticulating obliquely; with circular scar.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume linear, or lanceolate; 7.5-9 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute; muticous, or mucronate. Upper glume lanceolate; 9.5-11.5 mm long; 0.75 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scaberulous. Upper glume apex acute; muticous, or mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma linear, or lanceolate; 13-14.5 mm long; chartaceous; without keel; 3-7 -veined. Lemma lateral veins with distinct primaries but obscure intermediates. Lemma surface puberulous. Lemma apex awned; 1 -awned. Principal lemma awn subapical; 5-10 mm long overall. Palea 9.5-10.5 mm long; 0.7-0.75 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 3.75 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex; apex fleshy. Hilum linear.
