Giacomo Giuseppe Federico Delpino was an Italian botanist who made early observations on floral biology, particularly the pollination of flowers by insects. Delpino introduced a very broad view of plant ecology and was the first to suggest pollination syndromes, sets of traits associated with specific kinds of pollinators. He wrote Pensieri sulla Biologia Vegetale in 1867 and this failed to gather sufficient notice due to it being written in Italian. He corresponded with Charles Darwin and was one of the first to speculate on the idea of "plant intelligence".
