Resumen:
Cardiospermum bahianum , a new species from Bahia, Brazil, is described, illustrated, and compared to its putative closest relatives C. anomalum and C. cuchujaquense . The new species is endemic to the caatinga vegetation. In addition, micromorphological characters of leaf epidermis, seed coat, and pollen grains are described. A somatic chromosome number of 2 n = 36 is reported. Detailed light and scanning electron microscope photographs of the main characters are presented. The new species belongs to Cardiospermum section Carphospermum . It is distinguished from the similar C. anomalum by its conspicuous lenticels, seeds nearly spherical, and it differs in chromosome number. Additionally, new synonymies for C. anomalum are established. A key to the species of Cardiospermum in Brazil is provided.
