Morphology General Habit
Perennial; caespitose. Culms geniculately ascending; 45-55 cm long. Culm-internodes striate; smooth; distally glabrous. Leaf-sheaths pubescent. Ligule an eciliate membrane; 0.5-1 mm long; membranous; lacerate. Leaf-blades 5-10 cm long; 2.5-4 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; effuse; nodding; 8-15 cm long. Primary panicle branches 3-5 -nate; 3-4 cm long; bearing 1-2 fertile spikelets on each lower branch. Panicle axis scaberulous; glabrous. Panicle branches flexuous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 10-20 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 30-45 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2 mm long; pubescent.
Fertile
Spikelets comprising 10-20 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 30-45 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2 mm long; pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar. Lower glume lanceolate; 5-6 mm long; 0.75 length of upper glume; chartaceous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume lateral veins prominent. Lower glume apex acute. Upper glume lanceolate; 8-8.5 mm long; 0.66 length of adjacent fertile lemma; chartaceous; 1-keeled; 5-7 -veined. Upper glume primary vein scabrous. Upper glume lateral veins prominent. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma 11-13 mm long; 5-7 -veined. Lemma lateral veins prominent. Lemma apex awned; 1 -awned. Principal lemma awn subapical; straight; 7-12 mm long overall. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 0.8-1 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
Distribution
Asia-temperate: China. Asia-tropical: India.
