Although Pliny held Democritus to be the greatest authority on the flora of Greece, among the authors whose work has come down to us it is Theophrastus who describes the greatest number of species, mentioned also by other authors both before and after him.
In the Greek world, interest in plants focused mainly on the possibility of utilizing them in all the different moments of daily life. This requisite is reflected in classical texts, especially as concerns their nutritional, economical and therapeutic uses.
Citations from classics cannot be verified, due to the difficulty in conducting palynological analysis. What is clear, however, is that some islands, such as Cyprus and Crete, served as a bridge between Mesopotamia and Greece for the exchange of species.
