Discussion | 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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eragrostis scaligera is known from Lee and Collier counties, Florida, where it grows in sandy areas in the coastal scrub zone and along adjacent roadsides, at 0-10 m. It is native to French Guiana and Brazil. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
