IACS500 Symposium

For the five hundredth anniversary of his birth, the Botanical Garden and Museum of the University of Pisa is celebrating Andrea Cesalpino, the second praefectus of the garden and a key figure in the birth of modern systematic botany.

Cesalpino was indeed the first to base the study of biodiversity on the recognition of diagnostic traits, and to classify plants into homogeneous, comparable groups, organized into increasingly broad and general hierarchical categories.

On this occasion, we are pleased to announce the IACS500 conference, which will be held in Pisa on June 5th and 6th, 2025. This event is aimed at researchers and scholars from around the world whose primary interest lies in systematics.

The event is sponsored by The Systematics Association, IAPT (International Association of Plant Taxonomists), the Italian Botanical Society, the Italian Society of Biogeography, the Italian Zoological Union, and the Italian Society of Protistology.
