Morphology General Habit
Perennial; culms solitary, or caespitose; clumped loosely. Culms 50-60 cm long. Culm-nodes black; pubescent. Leaf-sheaths longer than adjacent culm internode; pilose. Leaf-sheath auricles absent, or falcate. Ligule an eciliate membrane; 1-3 mm long; brown; glabrous on abaxial surface, or pubescent on abaxial surface; entire, or erose; truncate. Leaf-blades erect; flat, or conduplicate; 12-24 cm long; 3-5 mm wide. Leaf-blade midrib keeled beneath. Leaf-blade surface glabrous, or pilose; hairy adaxially, or on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; nodding; 12-24 cm long. Primary panicle branches spreading; 2-4 -nate; 5-10 cm long; bearing 1-3 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 12-20 mm long; 5-8 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-2 mm long; pubescent.
Fertile
Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 12-20 mm long; 5-8 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-2 mm long; pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 8-12 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acuminate, or setaceously attenuate. Upper glume lanceolate; 11-17 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface pubescent. Upper glume apex acuminate, or setaceously attenuate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 10-15 mm long; chartaceous; without keel; 5 -veined. Lemma surface pubescent, or pilose. Lemma apex entire, or dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; reflexed; 8-14 mm long overall. Palea oblong; 8-10 mm long. Palea keels contiguous above a sulcus. Palea surface puberulous; hairy on back. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
