Abstract: Chromosome numbers were counted for 23 species of Crotalaria native to Brazil. Among these data there were new counts for 15 taxa, and some confirmed previous reports or represented numbers that were different from those cited previously. The chromosome numbers most frequently found were 2n = 16 and 2n = 32. Only C. incana L. had 2n = 14 and C. tweediana Benth. had 2n = 54. The counts 2n = 32 and 54 were found in species of section Calycinae and 2n = 16 and 14 in species of section Chrysocalycinae. The data revealed the importance of chromosomal parameters in the characterization of sections Calycinae and Chrysocalycinae in Brazil. We discuss the systematic significance and evolutionary aspects for the genus, comparing the results with the two sections that are native in Brazil.
