Eragrostis barrelieri is a European species that is now naturalized in the Flora region, primarily in the south-western United States. It grows on gravelly roadsides, in gardens, and other disturbed, sandy sites, especially near railroad yards, at 10-2000 m. The ring of glandular tissue is most conspicuous below the upper cauline nodes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
