Potentilla wilderae, commonly known as Barton Flats horkelia, is a rare species of flowering plant in the rose family. It is endemic to San Bernardino County, California, where it is known from only about ten occurrences in the vicinity of Barton Flats. It grows in the montane chaparral and woodlands habitat where chaparral meets pine forest, and it is threatened by logging.
