NHN

The Nationaal Herbarium Nederland An institute for systematic botany of the universities of Leiden, Utrecht and Wageningen (The Netherlands)

The Nationaal Herbarium Nederland (National Herbarium of the Netherlands, NHN) was established in 1999 as the decentral merger of three major university herbaria in Leiden (L, better known as the Rijksherbarium), Utrecht (U) and Wageningen (WAG, Herbarium Vadense): decentral to safeguard the training of students in systematic botany at these three universities with broad training programmes in "green" biology; merged to optimise co-operation in research, training and collection management, and to better comply with demands to underpin (inter)national policies on conservation and sustainable use of biodiversity. The training of taxonomists and herbarium curators from developing countries is considered a major task in this respect.
	NHN Wageningen
With a collection of close to over 5.5 specimens, the NHN is one of the largest herbaria in the world. All ca. 50,000 type-specimens have been made available on internet. The three libraries of the NHN are a unique resource covering botanical and mycological literature from the 16th century to the present. The NHN works closely together with the botanical gardens of the three participating universities, which in turn harbour a wealth of living specimens of over 30,000 species, including very large vouchered research collections.
