''Haploesthes greggii'', false broomweed, is a North American species of flowering plants in the daisy family. 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 map )〕〔(SEINet, Southwestern Biodiversity, Arizona chapter ''Haploesthes greggii'' Gray ) photos, description, distribution map〕 The genus name is sometimes spelled ''Haploësthes,'' with two dots over the first e to indicate that the o and the e are to be pronounced in separate syllables. This is optional; either spelling is equally acceptable.〔〔 (International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) ) section 60.6〕 ''Haploesthes greggii'' is a perennial herb or subshrub up to tall, somewhat succulent. Leaves are very narrow, sometimes thread-like. The plant produces numerous yellow flower heads in flat-topped arrays. Each head has 3–6 ray flowers and 18-100 disc flowers.〔 ;Varieties〔〔(Flora of North America, Haploësthes A. Gray, 1849. )〕 *''Haploesthes greggii'' var. ''greggii'' *''Haploesthes greggii'' var.
