    [GB]
    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms scandent; slender; pendulous at the tip; woody. Culm-internodes terete; thick-walled; retrorsely scabrous; distally glabrous. Lateral branches fastigiate. Branch complement many; in a clump; subtended by a bare patch above the node; with subequal branches. Leaf-sheaths glabrous on surface, or puberulous. Leaf-sheath oral hairs ciliate; deciduous. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath; petiole glabrous. Leaf-blades deciduous at the ligule; lanceolate; 6-8 cm long; 10-12(-30) mm wide. Leaf-blade venation with 7 secondary veins. Leaf-blade surface puberulous; hairy abaxially. Leaf-blade margins smooth.
    Inflorescences
    Inflorescence composed of racemes; terminal and axillary. Racemes 1; single; straight; bilateral; 6-8 cm long; bearing 3-5 fertile spikelets on each. Spikelet packing lax. Rhachis internodes 10-15 mm long. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 3-5 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 15-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3.5 mm long; pubescent.
    Fertile
    Spikelets comprising 1 basal sterile florets; 3-5 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 15-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3.5 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels. Lower glume apex obtuse. Upper glume lanceolate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; persisting on inflorescence. Lemma of lower sterile floret similar to fertile lemma. Fertile lemma lanceolate; 7 mm long; chartaceous; without keel. Lemma apex obtuse; pubescent; mucronate. Palea 1 length of lemma. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 3. Anthers 3; 3 mm long. Stigmas 2. Ovary umbonate.
    Fruits
    Caryopsis with adherent pericarp.
    Distribution
    South America: Caribbean.

Leaf-blade surface glabrous. Leaf-blade margins smooth. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight; bilateral; 5-10 cm long; bearing few fertile spikelets; bearing 4-7 fertile spikelets on each. Spikelet packing broadside to rhachis; distant. Spikelets appressed; solitary. Fertile spikelets sessile.
