De plantis libri 16. Andreae Caesalpini Aretini, medici clarissimi, doctissimique, atque philosophi celeberrimi ..., Firenze, 1583.
With the De Plantis, divided into 16 chapters, Andrea Cesalpino, physician and botanist from Arezzo, pupil of Luca Ghini, tried to go beyond a description of the plants based, until then, on their use and properties, by introducing a careful examination of their intrinsic characteristics (morphology, physiology, etc.).
A peculiar feature of this text is that it contains no figures, in a historical moment when detailed representations of plants were beginning to appear.
On the title page it is visible a stamp of the Webbian Library (books that belonged to Philip Barker Webb).
Out of the works of A. Cesalpino (1519-1603) the University of Florence, preserves, in its Museum of Natural History, the rich herbarium, considered one of the oldest in the world.
