Haploesthes greggii, common name false broomweed,[2] 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).[3][4][5]

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.[3][6]
Haploesthes greggii is a perennial herb or subshrub up to 80 cm (31 in) 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.[3]
