Someone who is interested in botany is probably to be found hunched over the pages of a herbarium. This compilation of plants that have been dried and preserved between the pages of a collection is the oldest tool of a naturalist. The ancient Greeks had already created herbariums to organise their study of plants. Today, the term “herbarium” can also refer to the organisation or institution which is dedicated to the conservation of such a collection. The herbarium belonging to the Pierre Fabre Botanical Conservatoire contains an extensive inventory of more than 7,000 species and is a reference in plant identification and expertise. Herbarium collections are invaluable tools in the knowledge of botanical heritage and are a rich legacy that the Klorane Botanical Foundation is working to protect. Moreover, shortly after the creation of the Institute in 1995, a donation was made to the Museum of Natural History in Paris towards the restoration of part of the Herbarium of Asian Solanaceae under the direction of professor Lu An-Ming.
