Morphology General Habit
Perennial; caespitose. Culms geniculately ascending, or decumbent; 15-30 cm long. Ligule an eciliate membrane; 2-4 mm long. Leaf-blades flat; 5-12 cm long; 1-2 mm wide. Leaf-blade surface glabrous. Leaf-blade apex obtuse.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; effuse; 8-14 cm long; 1.5-5 cm wide. Primary panicle branches spreading; 2 -nate; 2-5 cm long. Panicle branches stiff; smooth. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 3-10 mm long; smooth.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension, or with a barren rhachilla extension. Spikelets elliptic; laterally compressed; 2.5-3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension, or with a barren rhachilla extension. Spikelets elliptic; laterally compressed; 2.5-3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 2.5-3 mm long; 1.1 length of upper glume; membranous; glandular (on veins); 1-keeled; 3 -veined. Lower glume apex obtuse, or acute. Upper glume lanceolate; 2.2-2.8 mm long; 1-1.2 length of adjacent fertile lemma; membranous; glandular (on veins); 1-keeled; 3 -veined. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 2.5 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins excurrent. Lemma surface asperulous; rough above. Lemma apex truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.3-0.4 way up back of lemma; geniculate; 2.5-4.5 mm long overall; with a straight or slightly twisted column. Palea 0.4 length of lemma; hyaline; 0-2 -veined; without keels, or 2-keeled. Rhachilla extension 0.1 length of fertile floret; pubescent.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 0.6-1 mm long.
