Eragrostis pilosa
Eragrostis refracta
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.

Eragrostis refracta grows in sandy pinelands, savannahs, marshes, and woodlands on the coastal plain of the southeastern United States, at 0-150 m. It is not known from Mexico.
