Two new species of Psyllocarpus sect. Psyllocarpus are here described and illustrated. Psyllocarpus bahiensis and Psyllocapus scatignae, from the campo rupestre s.l. of Bahi and Minas Gerais states, respectively. We provide comments on their distribution, habitat, conservation status, and taxonomy. In addition, we analysed floral, fruit, and seed micromorphology, as well as pollen grains of the new species. We also provide an updated identification key to the species of P. sect. Psyllocarpus.
