Gyali is a small volcanic island with a surface of 4.63 km2 in the SE Aegean Sea. Flora and vegetation of its main natural ecosystems and their ecological conditions are examined. The main vegetation units on Gyali are: Pinus brutia forest, scrubs and phrygana, psammophilous and halophytic communities. A total of 241 native taxa (species and subspecies) are reported, including 149 new records for the island. Analysis of the flora based on ecological indicator values shows that 29 % of the taxa are indicators of extreme warmth and 72 % of very dry or dry habitats. 43 % are acidophilous or calcifuge taxa and 45.2 % halotolerant taxa, or facultative or obligatory halophytes.
