The aim of this work is to provide a contribution to the flora of Sifnos Island and Kitriani Islet by analyzing the distribution patterns and endemism of their vascular flora. The total flora of Sifnos Island consists of 95 families, 381 genera and 776 taxa including alien species. A comparison, albeit partial, with the first florula of the island compiled by Malakates in 1933 was also made, highlighting the landscape changes that have occurred over the years due to the dessication of the island following human exploitation of its resources. Also in the present paper, 26 additional species for both islands are added as new records. In particular for the island of Sifnos, Gagea pseudopeduncularis, Limonium oligotrichum and L. sitiacum new for the phytogeographic region of the Kiklades, Campanula heterophylla and Galanthus ikariae, endemic species with a rather restricted distribution in the Aegean area.
