Morphology General Habit
Perennial. Culms decumbent; 40-120 cm long; 1-2 mm diam.; rooting from lower nodes. Culm-internodes distally glabrous. Culm-nodes glabrous, or pubescent. Lateral branches ample. Leaf-sheaths glabrous on surface, or pilose; with tubercle-based hairs; outer margin hairy. Ligule an eciliate membrane; 0.2-0.4 mm long; erose. Leaf-blade base cordate; asymmetrical; with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 5.5-12 cm long; 8-12 mm wide. Leaf-blade surface glabrous, or pilose; sparsely hairy; with tubercle-based hairs.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; terminal and axillary. Axillary inflorescences different from terminal (spikelets cleistogamous, pubescent). Panicle open; pyramidal; 13-30 cm long; 13-26 cm wide. Primary panicle branches 1-2 -nate. Panicle branches bearded in axils. Spikelets appressed; solitary, or in pairs. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; obtuse; 3.1-3.6 mm long; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; obtuse; 3.1-3.6 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 2.2-2.6 mm long; 0.75 length of spikelet; membranous; without keels; 3 -veined. Lower glume lateral veins prominent. Lower glume apex obtuse. Upper glume ovate; 2.9-3.2 mm long; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume lateral veins prominent. Upper glume apex obtuse.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 2.4-3.1 mm long; 1 length of spikelet; membranous; 7 -veined; prominently veined; acute. Fertile lemma obovate; dorsally compressed; 2.4-3.1 mm long; indurate; shiny; without keel. Lemma margins involute. Lemma apex obtuse. Palea involute; indurate.
Morphology Reproductive morphology Flowers
Anthers 3; 1.1-1.7 mm long; orange.
Distribution
South America: northern South America, western South America, Brazil, and southern South America.
