Discussion | Specimens of Gaillardia coahuilensis were earlier treated as members of G. mexicana A. Gray, a Mexican species. Plants of G. coahuilensis seem much closer to G. pulchella than to G. mexicana in most attributes and might be included within the circumscription of G. pulchella but for the short hairs on the corollas.
