Descriptions

Morphology General Habit
Perennial. Culms scandent; 200-300 cm long; 2-3 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; 9.5-15 cm long; distally glabrous. Culm-nodes without obvious supra-nodal ridge. Lateral branches dendroid; infravaginal. Bud complement 20-36. Branch complement many; in a horizontal line; with 1 branch dominant; as thick as stem. Culm-sheaths persistent; 9.8-11.2 cm long; retrorsely scabrous; hairy on margins. Culm-sheath blade triangular; indistinctly demarcated from sheath; erect; 0.9-1 cm long; glabrous on surface. Leaves 7-10 per branch. Leaf-sheaths pilose; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule an eciliate membrane; 0.3-0.5 mm long; truncate. Collar with external ligule; glabrous. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1 cm long; petiole pilose. Leaf-blades lanceolate; 3.5-7.1 cm long; 2.5-5 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface pubescent; densely hairy; hairy abaxially. Leaf-blade margins ciliate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; bracteate at branch bases and bracteate at pedicel base (rarely). Panicle open; oblong; 2 cm long. Primary panicle branches ascending; 0.5 cm long. Panicle axis pubescent (below). Panicle branches angular; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-2 mm long; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 5.5-5.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 5.5-5.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.9-1.1 mm long; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acute. Upper glume ovate; 1.2-1.7 mm long; 0.2 length of adjacent fertile lemma; membranous; without keels; 1-3 -veined. Upper glume lateral veins absent, or obscure. Upper glume surface pubescent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 2.5-2.7 mm long; 0.5 length of fertile lemma; chartaceous; 3 -veined; pubescent; hairy below; acute. Lemma of upper sterile floret ovate; 4.5-5.2 mm long; chartaceous; pubescent; acute. Fertile lemma ovate; 4.7-5 mm long; coriaceous; without keel; 7 -veined. Lemma surface pubescent. Lemma apex acute. Palea 5-5.5 mm long; 4-6 -veined. Palea surface scabrous.
Morphology Reproductive morphology Flowers
Lodicules 3; 0.9-1.4 mm long; membranous; ciliate. Anthers 3; 2.6 mm long. Stigmas 2.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; apex unappendaged.
Distribution
South America: Brazil.
