Haploesthes greggii, common name false broomweed, is a North American species of flowering plants in the family Asteraceae. It grows in northeastern Mexico (Chihuahua, Coahuila and Nuevo León) and in the south-central and southwestern United States (Texas, Oklahoma, New Mexico; also historical reports of the species in Colorado and Kansas but very likely extirpated there).Biota of North America Program 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapter Haploesthes greggii Gray photos, description, distribution map
