A new species in the genus Kallstroemia (Zygophyllaceae), K. hageri Rebman, endemic to the Baja California peninsula is described here for the first time. It is similar to K. peninsularis D.M. Porter in having retrorse pubescence on its stems and pedicels, but differs in its smaller flowers, shorter fruit beak, shorter pedicels, and fewer leaflet pairs per leaf. This new species occurs mostly in the midpeninsular region and ranges from the Sierra de La Libertad in the southern part of the state of Baja California south to the vicinity of Cerro Mechudo in the southern Sierra de La Giganta of Baja California Sur. A botanical illustration and a key to the species in the genus Kallstroemia from the Baja California peninsula are also presented.
