Resumen:
Abstract-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 also described. A somatic chromosome number of 2n= 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 possessing conspicuous lenticels, seeds nearly spherical, and differs in chromosome number. Additionally, new synonymies for C. anomalum are established. A key to the species of Cardiospermum in Brazil is provided.
