Gaillardia is a member (tribe) of the family Compositae. There are at least twenty-eight species occurring in this country; the majority of these occur naturally but many are under cultivation as well. The territorial range in the United States is from the Atlantic to the Pacific and from Canada to Mexico. The members of this tribe flower anywhere from March until the late fall, dependent mainly on the climate of the particular locality. Those growing in this region bloom from June until the first frost.1 Because of the ubiquity of this plant, because we cannot find any reference in the literature to sensitizations produced by it and because we believe it to be a not uncommon irritant, we deem it worth while to draw the attention of the medical profession to this plant as a possible cause of certain cases of dermatitis venenata.2
