    [GB]
    Habit
    Annual. Cataphylls evident. Culms 60-140 cm long. Leaf-sheaths keeled; glabrous on surface; outer margin glabrous, or hairy. Leaf-sheath oral hairs lacking, or ciliate. Ligule a fringe of hairs; 1.3-1.8 mm long. Leaf-blades 16-25 cm long; 8-20 mm wide. Leaf-blade surface scabrous; glabrous, or pilose; sparsely hairy.
    Inflorescences
    Inflorescence a panicle. Panicle spiciform; linear; dense (internodes 0.8-1.7mm); 7-18 cm long; 1.3-1.6 cm wide. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; scaberulous; glabrous, or pubescent; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 2-4 in the cluster. Involucre composed of bristles; connate into a cup below; with 3 mm connate; globose; 6.8-9.6 mm long; base obconical; base pubescent. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; 20-30 in principal whorl; inner bristles longer than outer; with one conspicuously longer bristle (16-30mm); 6-7 mm long; flattened; without grooves; rigid; antrorsely scaberulous; glabrous, or pubescent; attenuate.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 5.5-6.8 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 5.5-6.8 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 2.2-2.9 mm long; 0.5 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 3.5-5.2 mm long; 0.6-0.75 length of spikelet; membranous; without keels; 5 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 5-6.1 mm long; 1 length of spikelet; membranous; 5-7 -veined; acute. Fertile lemma ovate; 5.2-6.6 mm long; coriaceous; much thinner on margins; without keel; 5 -veined. Lemma margins flat. Lemma apex obtuse. Palea coriaceous.
    Flowers
    Anthers 1.9-2.4 mm long.
    Fruits
    Caryopsis with adherent pericarp.
    Distribution
    North America: Mexico. South America: Mesoamericana.
