The chromosome complements of shrubby Oxalis species from South America

Twenty species of shrubby Oxalis species native in South America were arranged in six groups according to their karyotype similarities. The first group includes more than half of the species studied, all with 2n = 12 relatively small metacentric chromosomes. The rest of the species from the other gr...
