A karyosystematic study of five characteristic taxa from the Ionian Islands (Greece) is presented. The cytogeography of Centaurea subciliaris is commented. The chromosome number of a newly studied Teucrium halacsyanum population from Lefkada island is given. The taxonomic position of Viola alba s. l. is also discussed and a microphotograph (for the first time) of its karyotype from Lefkada island is provided. The chromosome number and karyotype morphology of Moraea mediterranea and Crocus speciosus subsp._ speciosus_ are confirmed on material from Lefkada island and the presence of the latter in the island is referred for the first time.
