Grindelia adenodonta,[2] Lonestar gumweed,[3] is a species of flowering plants in the daisy family.

Grindelia adenodonta is native to the southern Great Plains of the United States, found only in the State of Texas.[4]

Grindelia adenodonta grows in prairies and thickets, and along streambanks. It is an annual herb up to 130 cm (52 inches or 4 1/3 feet) tall. Leaves are narrowly egg-shaped or triangular, up to 9 cm (3.6 inches) long. The plant usually produces numerous flower heads in open, branching arrays. Each head has 20-27 ray flowers surrounding a large number of tiny disc flowers.[2][5]
