Morphology General Habit
Perennial; caespitose. Culms erect, or geniculately ascending; 15-50 cm long. Leaf-sheaths open for most of their length; glabrous on surface. Ligule an eciliate membrane; 2.5-3.6 mm long; acute. Leaf-blades involute; 3-4 mm wide. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade margins scaberulous. Leaf-blade apex obtuse.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; loose; 15-20 cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; compressed slightly; 5-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long; smooth.
Fertile
Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; compressed slightly; 5-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long; smooth.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume oblong; 1-1.5 mm long; 0.66 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 3-3.5 mm long; 0.66-0.75 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 4.4-4.6 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma apex obtuse. Palea 4-4.2 mm long; 2 -veined. Palea keels ciliolate; adorned above. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 0.5-0.8 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ovoid; 0.8 mm long. Hilum punctiform.
Distribution
South America: southern South America.
