HABIT Perennial. Rhizomes short; pachymorph. Culms woody. Culm-internodes terete. Culm-nodes without obvious supra-nodal ridge. Lateral branches dendroid. Bud complement 1. Leaf-sheath oral hairs setose; 20 mm long. Ligule an eciliate membrane; 1–2 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2–0.3 cm long; petiole glabrous. Leaf-blades lanceolate; 12–15 cm long; 20 mm wide; stiff. Leaf-blade venation with 12 secondary veins; with distinct cross veins. Leaf-blade margins smooth. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; oblong; dense; 13–18 cm long; with spikelets clustered towards branch tips. Primary panicle branches 1 -nate; 5–10 cm long. Panicle axis smooth. Panicle branches capillary; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 6 fertile florets; with diminished florets at the apex. Spikelets linear; subterete; 30 mm long; 2.5 mm wide; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 3 mm long; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute; mucronate. Upper glume lanceolate; 4 mm long; membranous; without keels; 5 -veined. Upper glume apex obtuse; mucronate.

FLORETS Fertile lemma ovate; 6 mm long; chartaceous; without keel; 7 -veined. Lemma surface pubescent; hairy at base. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn 2 mm long overall. Palea 1 length of lemma. Palea keels scaberulous.

FLOWER Lodicules 3; ciliate. Anthers 3; 4 mm long. Stigmas 2.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION South America: Brazil.
