Grindelia scabra, the rough gumweed,[1] is a rare North American species of flowering plants in the family Asteraceae. It has been found in northern Mexico (Coahuila) and the southwestern United States (western Texas and southern New Mexico).[2][3]
Grindelia scabra grows in dry rocky slopes and on top of mesas (flat-topped hills). It is an annual, biennial, or perennial herb up to 70 cm (28 in) tall. The plant usually produces numerous flower heads in open flat-topped arrays. Each head has 17-30 ray flowers, surrounding a large number of tiny disc flowers.[4]
