Carlo Bertero (1789–1831) is among the most famous Italian botanical collectors that have contributed toward our knowledge of the neotropical flora. A preliminary study of Bertero's letters, field books and herbarium label data preserved at the library and herbarium of the Department of Plant Biology of the University of Turin provides important information about the itineraries and the chronological sequence of Bertero’s expedition to the Antilles (1816–1821). This study is part of an ongoing project where a complete biography of Carlo Bertero and his botanical work in the New World and the South Pacific will be published in the near future (Delprete, Forneris & Pistarino, in progress).
