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.) |
The range of Eragrostis curtipedicellata extends from southern Colorado, Kansas, and Missouri to northeastern Mexico. It grows near fields, along roadsides, and in the margins of woods, at 10-1525 m. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
