There are 7 yellow- or yellowish-green-flowered Fritillaria species in Greece, 4 of which are endemic. F. conica and F. euboeica, endemie to mainland Greece and Evvia, are distinct by their 3-fid styles. F. rhodia is restricted to the island of Rodos. F. pelinaea, here described as a new species from Mt Pelineo on the island of Hios, was previously confused with F. carica and F. bithynica, found both on the East Aegean islands and in Asia Minor. The presence on the island of Samos of F. forbesii is reported, which is a new record for Greece. The main morphological features of the seven species are described and compared with those of related species. The karyotypes of F. rhodia and F. pelinaea are presented for the first time, that of F. bithynica was studied on a newly discovered population. Some differences in karyotype morphology are reported, especially in the marker and SA T chromosomes. The oceurrence of yellowish-green variants in normally purplish-flowered Fritillaria species is discussed
