The study was based on floristic-morphological analysis specimens deposited ASE, CEN, EAC, ESA, HCDAL, HST, HUEFS, HUVA, HVASF, IPA, PEUFR, and UFP herbaria, specialized bibliography, typus collections available on-line platforms, field observations. In we registered 13 species Evolvulus: E. anagalloides, cardiophyllus, eleaegnifolius, ericifolius, filipes, glomeratus, gypsophiloides, linoides, nummularius, ovatus, phyllanthoides, pterocaulon, sericeus. Of these, ten occur protected areas from Ceara state. greatest richness for genus (10) open crystalline caatinga. Additionally, an identification key, morphological descriptions, geographic distribution, ecological comments, phenology illustrations diagnostic characters species.
