Morphology General Habit
Perennial; caespitose. Culms erect, or geniculately ascending; 45-120 cm long. Leaf-sheaths hispid; with reflexed hairs. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 1-3 mm long; erose. Leaf-blades drooping; 10-25 cm long; 4-12 mm wide; dark green. Leaf-blade surface scaberulous; glabrous, or pubescent; sparsely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle glabrous, or pubescent above (obscurely); tipped by a glumaceous appendage. Panicle contracted; oblong; nodding; 12-20 cm long. Primary panicle branches appressed; 1-3 -nate; 3-7.5 cm long; bearing 1-3 fertile spikelets on each lower branch. Panicle branches flexuous; scaberulous. Spikelets pendulous; solitary. Fertile spikelets pedicelled. Pedicels filiform; 3-6 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 15-25 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 15-25 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; dissimilar; shorter than spikelet. Lower glume linear; 5-9 mm long; 0.7-0.8 length of upper glume; chartaceous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 8-11 mm long; 0.7-0.9 length of adjacent fertile lemma; chartaceous; 1-keeled; 3 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 10-14 mm long; chartaceous; much thinner on margins; without keel, or keeled; lightly keeled; 5 -veined. Lemma surface scaberulous; hirsute (near margins). Lemma apex entire; awned; 1 -awned. Principal lemma awn subapical; 3-8 mm long overall; limb scabrous. Palea 0.8 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 1.5-3 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
