Eragrostis pilosa
Eragrostis cumingii
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 cumingii is native to southeast Asia and Australia. Within the Flora region, it has become established in Florida, growing in waste places and along roadsides in sandy or gravelly soils, at 0-150 m.
