Eragrostis refracta
Eragrostis ciliaris
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.

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.

1. Panicles 0.2-1.5 cm wide, contracted, the branches mostly appressed to the rachises, congested, forming glomerate lobes; spikelets densely packed | var. ciliaris |
1. Panicles 1.5-5 cm wide, open, the branches spreading 20-50° from the rachises; spikelets widely separated from each other | var. laxa |
