Grindelia oolepis, the plains gumweed,[2] is a North American species of flowering plants in the family Asteraceae. It is native to the south-central United States, having been found only in the State of Texas.[3]
Grindelia oolepis grows in black clay soils. It is a perennial herb up to 70 cm (28 in) tall. The plant usually produces only one flower head per stem. Each numerous disc flowers but no ray flowers.[1]
Some authors spell the epithet as oölepis, with two dots over the second o to indicate that each o is to be pronounced in a separate syllable. The dots are optional; either spelling is equally correct.[4]
