Founded in 1963, the Herbarium of the IRD Noumea (NOU) is a regional herbarium, occupying a room of 85 m² dedicated to collections. The samples are stored in wooden racks. Fruit specimens are stored in plastic containers. The silicate and alcohol specimens are stored in a refrigerator. The herbarium collection consists of approximately 85,000 specimens of vascular plants, including 700 types (mainly isotypes). 90% of the collection is dedicated to the flora of New Caledonia and the remaining 10% of the flora of other Pacific regions (Australia, Fiji, New Zealand, Vanuatu, Wallis & Futuna). The collection also includes 400 fruit specimens and hundreds of samples conserved in silicate and alcohol. The taxonomy is based on the taxonomic database “Florical” of the indigenous flora of New-Caledonia (Morat et al., in press).
