Panicles (8)15-30 cm long, 3.5-8 cm wide, open, diffuse, cylindrical; lower nodes with 1-2(3) branches; primary branches 0.6-5 cm, capillary, spreading 30-70° from the rachises, without spikelets on the lower 1/2; secondary branches spreading; pedicels 0.5-5 mm. Spikelets 0.7-1.1 mm, plumbeous to purplish. Glumes unequal, obovate to ovate, membranous; lower glumes 0.1-0.4 mm, occasionally absent; upper glumes 0.2-0.5 mm; lemmas 0.7-1.1 mm, elliptic, membranous, glabrous, acute to obtuse; paleas 0.7-1.1 mm, elliptic, membranous; anthers 0.2-0.3 mm, yellowish.

Sporobolus tenuissimus is native to the Western Hemisphere, and introduced to Africa and Asia. Its native distribution in the Americas is tropical, extending from southern Mexico to Brazil and Paraguay. It has been found at a few locations in the southeastern United States, at 0-100 m. It grows in disturbed areas, often occurring as a weed in gardens and cultivated fields.
