The present update to the flora of the island of Limnos in the North Aegean, based on our field studies in 2016 and 2018–2021, raises the currently known number of vascular plant species to 960 native taxa, 63 established neophytes and 27 species of as yet casual status, a total of 1,050 taxa. To substantiate these figures, we provide a catalogue of about 740 annotated records of 264 plant taxa, of which 231 taxa were not previously known to occur in the island. Sixty-eight taxa were found as new to the flora of the North Aegean biogeographic region. Among the biogeographically most significant of the newly recorded native species are Campanula lavrensis, Lactuca aculeata, Leontodon longirostris, Secale strictum subsp. anatolicum and Trifolium pachycalyx. The new finds strengthen the biogeographic affinities of Limnos with the Aegean islands further south. Most of the records were from agricultural landscapes and small-scale habitats. Several richness focus areas of newly recorded plants were identified. As a conclusion, the alleged species poverty of Limnos cannot be confirmed.
