Eragrostis bahiensis
Eragrostis pilosa
Eragrostis bahiensis grows in sandy soils near river banks, lake shores, and roadsides, at 0-200 m. Its range extends south from the Gulf Coast of the United States through Mexico to Peru, Bolivia, Paraguay, and Argentina.

Eragrostis pilosa is native to Eurasia but has become naturalized in many parts of the world. In the Flora region, it grows in forest margins and disturbed sites such as roadsides, railroad embankments, gardens, and cultivated fields, at 0-2500 m.
