Chromosome number of the Oxalis tuberosa alliance (Oxalidaceae)

Twelve taxa of the Oxalis tuberosa alliance were analysed and found to share the same basic chromosome number x = 8. The karyotypes are composed by small metacentric and submetacentric chromosomes. Different ploidy levels were found among the taxa: there were 9 diploids, 1 tetraploid, 1 hexaploid an...
