The Natural History Society of the Ardennes has 5 remarkable ancient herbaria, one of which has 240 volumes.

A few precious plates will be exhibited at the Heritage Department and, Arnaud Bizot, Vice-President of the SHNA (Société d'Histoire Naturelle des Ardennes), will introduce us to the herbaria Callay, Janet, Cardot, Mailfait and Bourguignon.
These collections, indispensable for typification and botanical studies, have a rich history: these botanists were also explorers and even, for one of them, a renowned psychologist, whose work inspired Freud. Presentation at the Heritage Reading Room at 11am and 3pm.
