The Nationaal Herbarium Nederland (NHN)
An institute for systematic botany of the universities of Leiden,
Utrecht and Wageningen (The Netherlands)
Core institute of the National Research School
Biodiversity
Partner in NLBIF
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.
With a collection of close to over 5.5 million 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 Universiteit Leiden Branch
The Universiteit Leiden branch of the NHN was
founded as the Rijksherbarium in 1829 by Royal Decree of King William I. It now houses a
collection of about 4.1 plant million specimens, including an extensive wood and
liquid-preserved collection, and is the custodian of some of the earliest European and
tropical herbaria of the 16ths and 17th century, and extensive icones collection and
unique botanical library.
The research and teaching programme is carried out by two project groups:
Plants of the IndoPacific Area
(PITA)
The research group Plants of the Indopacific (PITA) brings together
the research on the vascular plants of the Malesian region.
The immense, and very incompletely known diversity of flowering plants and ferns of the
Malesian region (Indonesia, Malaysia, the Philippines, Papua New Guinea, Singapore and
Brunei Darussalam) and adjacent Thailand and Indochina is central to the programme of this
research group. It co-ordinates the international Flora Malesiana project, a first
scientific inventory of about 42,000 flowering plants and ferns carried out by a voluntary
network of over 120 taxonomists all over the world, and all major herbaria in the Malesian
region. Selected species-rich genera from widespread families (currently Annonaceae,
Cucurbitaceae, Euphorbiaceae, Leguminosae, Orchidaceae, Poaceae, Urticaceae and various
Pteridophytes) are singled out for semi-monographic, phylogenetic and biogeographical
analysis, using macromorphology, characters from pollen, leaf and wood anatomy, and DNA
sequences.
The historical biogeography of the Malesian archipelago with its complex geological
history and mixture of gondwanic and laurasian flora elements is also a focus of study.
The group works closely together with the MOFEC-Tropenbos
programme in East Kalimantan to provide user-friendly field guides to primary and
secondary forest tree species and develop biodiversity indicators for disturbance and
regeneration. The ethnobotany and vegetation of Papua (Irian Jaya) is studied in the
framework of the interdisciplinary ISIR programme. Electronic user-friendly identification
tools are developed together with ETI (Amsterdam) in
the form of interactive CD-ROMs on major Malesian plant families such as Orchidaceae and
Leguminosae.
Phanerogams and Cryptogams of the
Netherlands and Europe (PCNE)
This research group combines specialists for the systematic study of flowering plants,
algae, mosses and fungi with emphasis on European taxa.
The Flora of the Netherlands is continuously updated, and jointly with the in-house
Foundation FLORON a database of over eight million plant records covering the last century
is maintained. This database (FLORBASE) is used to study the effects of anthropogenic
factors and climate change on the wild flora.
Freshwater and marine algae, of immense importance for the quality of our environment,
are the subject of detailed systematic, floristic, and phylogenetic research using
microscopic, ultrastructural and molecular markers. Their potential role as indicators of
ecosystem biodiversity is also studied.
The Macrofungi of the Netherlands are subject of a critical taxonomic study in the
long-term project on the Flora agaricina neerlandica. Selected groups are singled out for
in-depth phylogenetic and population biological research using morphology, DNA sequences
and AFLPs.
Although currently lacking bryological staff, the wealth of floristic information
associated with the moss collections are made accessible by the group to outside users for
environmental monitoring.
The Utrecht University branch
The Utrecht University herbarium
dates back to 1816. At present the collections include over 800,000 herbarium
specimens and 40,000 wood samples, mainly from tropical America (the
Neotropics). The Board of Utrecht University
have decided to close the Utrecht Herbarium
in 2008, making the research facility
inaccessible to researchers. The management of the
National Herbarium Nederland has issued an
official statement on this decision.
Until its closure, the Utrecht University herbarium housed two long-term
research projects: The Annonaceae Project, and The Flora of the Guianas Project.
The Annonaceae Project
The Annonaceae or soursop family constitute a large pantropical family of about 120
genera with over 2,500 species of trees, shrubs and lianas, and is studied by an
international multidisciplinary team, co-ordinated by the Utrecht branch of the NHN,
through the Annonaceae Newsletter and bi- to triannual workshops. The work of the Utrecht
team focuses on monographic and phylogenetic research of selected genera, a phylogenetic
analysis of the family using morphological characters and DNA sequences, the compilation
and updating of bibliographical and nomenclatural data, and dissemination of floristic and
biogeographical information through CD-ROMs (in co-operation with ETI-Amsterdam) and Internet.
The Flora of the Guianas
The Flora of the Guianas Project covers the geographical area of Guyana, Suriname, and
French Guyana and is well known for its high biodiversity, with over 8,000 species of
flowering plants. Studies by Utrecht staff members on several families, e.g.,
Bromeliaceae, Caryocaraceae, Euphorbiaceae, Gentianaceae, and Piperaceae are in progress.
Wood anatomical studies form an integrated part of the treatments of woody families. The
Flora of the Guianas Project is a co-operative project of institutions in ten different
countries. The Editorial Office is housed in the Utrecht Herbarium.
In co-operation with the Tropenbos Foundation the forest biodiversity in Guyana is
studied, and the impact of logging on its species richness analysed. Another applied
project deals with the use of Non-Timber Forest Products (NTFP) by Amerindians in the
North-West Districts of Guyana.
The Wageningen University Branch
The year 1896 can be seen as the foundation date of the Herbarium Vadense, now the
Wageningen University branch of the
National Herbarium, although substantial herbarium collections were already present in
Wageningen before that date. The collections are focused on the flora of tropical Africa,
and on cultivated plants and their wild relatives, and consist of approximately 800,000
specimens, supplemented by about 20,000 liquid-preserved specimens and 5000 wood samples,
numerous botanical illustrations and a specialised library.
The research programme includes taxonomic and phylogenetic and biogeographical research
of selected African plant families (Apocynaceae, Begoniaceae, Caesalpinoideae,
Dracaena), contributions to floras, economic botany, and the (bio)systematics of
cultivated plants and their wild relatives (especially Solanum and Lactuca),
using morphological, cytological data, DNA sequences and AFLPs.
The herbarium plays a major role in several international projects in various African
countries and supports various projects of the Tropenbos Foundation.
Since 1980 there is a strong link with the National Herbarium of Gabon, focused on the
training of scientific and technical personnel and the improvement of the collection
management in Gabon.
The ECOSYN project is carried out jointly
with the Department of Forestry of Wageningen University, and will produce lists of rare
and endangered species, an ecological atlas, a field guide and a manual for ecological
management of the forests of Tropical West Africa.
The Flora of Benin project aims at
providing a good National Herbarium to contain 40,000 specimens and issuing an analytical
flora.
The PROSEA foundation, a co-operative programme
between Wageningen University and a number of Southeast Asian countries has almost
completed a unique multivolume handbook and a comprehensive database on all presently
known information on the plant resources of Southeast Asia. A project with the same
concept has meanwhile been initiated for Tropical Africa (PROTA).
Gardens
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.

Mission Statement
The mission of the Nationaal Herbarium Nederland is to generate, provide
access to, and transfer knowledge on the nature, extent and origin of botanical diversity
of our planet, making use of its extensive herbarium collections and associated
information. It thus helps to provide a comparative base for all botanical sciences and to
contribute to the conservation and sustainable use of natural resources.
Research themes and research plan
The immense and largely poorly known botanical diversity of our planet requires a
broad, multifaceted, yet clearly prioritised approach. The research programme NHN fully
complies with the priorities recognised by the international community (Diversitas,
Systematics Agenda 2000, Global Taxonomy Initiative of the Convention of Biological Diversity) and the
National Research School Biodiversity and addresses the following major themes:
taxonomy of important groups of plants and macrofungi (for regional and world
monographs, regional floras, etc.)
biodiversity assessments (based on herbarium data, field inventories, and monitoring of
floristic change)
phylogeny and biogeography (using morphological, anatomical and molecular attributes and
cladistic analysis)
speciation and population differentiation
management and dissemination of taxic biodiversity information (in user-friendly
electronic form and hard copy, and fully exploiting the wealth of information linked with
collections, and scattered in the specialised literature)
The official Research plan for the current period
(2004-2008) is available as a PDF-file.

BSc, MSc and PhD Training Programmes
In addition to the participation in the biology curriculum at all three participating
universities, the NHN offers specialised MSc and PhD programmes, as part of its role as
core institute of the national Research (graduate) school Biodiversity. The Universiteit
Leiden branch offers, jointly with the department of Biopharmacy, an MSc course in
Biodiversity and Natural Products sponsored by NUFFIC, targeted at students from
developing countries. Specialist courses are given on "Biodiversity assessment",
"Biogeography", "Ethnobotanical Knowledge Systems", "Economic Botany", and
"Plant Families of Southeast Asia". The Utrecht branch teaches a course on Neotropical Flora.
