Eragrostis ciliaris
Eragrostis gangetica
Eragrostis ciliaris is native to the paleotropics. It is naturalized in parts of the United States, growing along roadsides, on waste sites, in xerothermic vegetation, and sometimes in saline habitats, at 0-200 m. It may be more widespread than indicated.

Eragrostis gangetica is an Asian species that now grows in the southeastern United States. It can be found in the sandy margins of ponds, roadsides, and ditches, at 0-100 m, usually in association with Pinus, Taxodium distichum, Rynchospora, and Steinchisma hians. Eragrostis gangetica is similar to E. bahiensis, but differs from that species in its annual habit and shorter spikelets, lemmas, anthers, and caryopses.
