The mitotic chromosome numbers of 40 accessions of 33 species of vascular plants collected in the Balearic Islands are presented. The triploid cytotype of Allium commutatum (2n = 24), the tetraploid cytotype of Scilla autumnalis (2n = 28), and the hexaploid (2n = 36) and octoploid (2n = 48) cytotypes of Tuberaria guttata are reported here for the first time in the Balearic archipelago. The tetraploid cytotype of Dactylis glomerata subsp. hispanica was not previously known from the Western Balearics, where it grows sympatrically with the diploid endemic D. glomerata subsp. ibizensis. The divergent chromosome number 2n = 26 is confirmed for Micromeria inodora. A new chromosome number (2n = 44) was determined for the restricted endemic Rubia balearica subsp. caespitosa. The existence of several infraspecific cytotypes bear phytogeographical significance.
