Species ID

Species-ID is dedicated to species descriptions and identification keys. It supports projects creating keys as well as projects creating species identification software.

IndExs – Index of Exsiccatae

"IndExs - Index of Exsiccatae" is a bibliography of exsiccatal series. With more than 2050 data entries it is nearly complete. "IndExs" comprises information on titles, abbreviations and bibliography of exsiccatae. Exsiccatae are defined here as "published, uniform, numbered sets of preserved specimens distributed with printed labels" (Pfister 1985).


Melastomataceae occur in all tropical biomes, are abundant, ecologically important, and comprise many horticulturally important species. The family comprises an estimated 3,000 "good" species in the Neotropics, 240 in Africa, 230 on Madagascar, and about 1,000 in Asia. One genus, Rhexia, is endemic in North America. The sister clade of Melastomataceae, Memecylaceae, comprises 500 species, most of them in the paleotropics. The site Melastomataceae.Net will present information on the biodiversity of these two families by providing a portal to open-access databases, starting with MEL names. MEL names is a service for accessing the ca.


An Information System for Characterization and DEtermination of EctoMYcorrhizae

The goal is
• to offer a online database system for multiple usage and therewith dissemination of expert knowledge especially by providing public access to database generated identification keys, natural language descriptions and illustrations of ectomycorrhizae
• to promote common standards on descriptive data connected with taxonomic names of ectomycorrhizae to facilitate interoperability and data exchange

LIAS – A Global Information System for Lichenized and Non-Lichenized Ascomycetes

LIAS is a multi-authored information system for the collection and distribution of descriptive and other biodiversity data on lichens and non-lichenized ascomycetes. The goal is

* to provide a working space for cooperation and collaboration of experts on ascomycetes in the Internet

Fauna Europaea

Euro+Med Plantbase


The scientific names of animal species are crucial to effective global communication about biodiversity, and hence its use and conservation. Without broad agreement on the name of a disease-bearing microbe, vital food species, or threatened animal, we can't even begin to combat, exploit or conserve them.



W3TROPICOS provides new and improved access to the Missouri Botanical Garden's VAST nomenclatural database and associated authority files. In this release (rev. 1.5), the following information is provided when present (* indicates a hypertext link to additional information about a name or reference):

International Plant Names Index (IPNI)


The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of all seed plants, ferns and fern allies. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. The data are freely available and are gradually being standardized and checked. IPNI will be a dynamic resource, depending on direct contributions by all members of the botanical community.


The aim of a World Register of Marine Species (WoRMS) is to provide an authoritative and comprehensive list of names of marine organisms, including information on synonymy. While highest priority goes to valid names, other names in use are included so that this register can serve as a guide to interpret taxonomic literature.

UBio NameBank

NameBank is a registry for all recorded taxon names.

NameBank is a biological name server. It stores and serves NameBankIDs via Life Science Identifiers, a persistent and distinct identifier. Each NameBank LSID returns a NameBank object which contains information about the NameBank record.

SYNTHESYS NAD: Providing itinerary related datasets and tools (for integration, visualisation and quality check)

The funtion of this service is to detect itinerary patterns in georeferenced primary data presumably collected during a collecting event.

DIALOBIS (DIALOgue Biological Identification System)

Dialobis Edition offers individual authors, companies and Publishing houses the possibility to publish scientific relevant documents - Monographs, Dissertations, Doctoral/Post doctoral thesis, Reports, Annual Reports, Congress Report, and Corporate identity - in electronic form on CD-ROM or DVD.

Our popular scientific CD’s are produced under the auspices of Dialobis (Dialogue Biological Identification System) - Software. Detailed information is put together at different pages.
