Welcome to ITIS, the Integrated Taxonomic Information System! Here you will find authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. We are a partnership of U.S., Canadian, and Mexican agencies (ITIS-North America); other organizations; and taxonomic specialists. ITIS is also a partner of Species 2000 and the Global Biodiversity Information Facility (GBIF). ... [Information of the supplier]
Species 2000 is a "federation" of database organisations working closely with users, taxonomists and sponsoring agencies. The goal of the Species 2000 project is to create a validated checklist of all the world's species (plants, animals, fungi and microbes). This is being achieved by bringing together an array of global species databases covering each of the major groups of organisms. Each database covers all known species in the group, using a consistent taxonomic system. The participating databases are widely distributed throughout the world and currently number 40. The existing global species databases presently account for some 40% of the total known species, so substantial investment in new databases will be needed for full coverage of all taxa to be achieved. ...

Bei der Ansprache schwierig zu bestimmender Pflanzenarten treten immer wieder Probleme auf. Die hier abrufbaren digitalen Bilder wichtiger Details können helfen, diese zu meistern. Sie bieten vor allem die Möglichkeit, ähnlich aussehende Sippen vergleichend nebeneinander zu betrachten. Dadurch fällt es wesentlich leichter, die in den Bestimmungsschlüsseln genannten Unterschiede zu erkennen. Die Bestimmungshilfen sind als Ergänzung zur "Flora von Thüringen" gedacht. Sie können aber auch den Umgang mit den meisten anderen Bestimmungsbüchern zur Flora von Deutschland erleichtern. ... [Information des Anbieters]
The Type Specimen Register of the United States National Herbarium was begun in 1966 and contains images and data for more than 90,000 type specimens of algae, lichens, bryophytes, ferns, gymnosperms and angiosperms. Yet to be imaged are the lichens, bryophytes and algae, as well as any type that has been on loan since before the start of the project. Types that have been imaged are indicated with a bold letter 'I' at the end of the record. The 'Guidelines and Resources' section describes some of our working methods and some issues with special collections. Types in the U.S. National Herbarium are filed under the basionym and all queries search only the basionym fields. Over time we have added the current name to some records as specimens are annotated, and this name is also displayed. Two search options are available. The 'quick search' leads directly to a single name. The 'full search' allows the user to select search fields, sort order, and output format. ... [Information of the supplier]
This site provides "various paths for exploration or comparison of four systems of flowering plant classification. Selection of a Family name will query an index of web links relating to that Family or included taxa. This 'gateway' system - eventually to include all vascular plants - is under constant revision. Current options (menu bar at the base of this page) include: Cronquist, Takhtajan, Thorne, APG (Angiosperm Phylogeny Group). ... [Information of the supplier, modified]
This site provides access to those specimen records and images available digitally through the Herbarium Catalogue. The Herbarium at the Royal Botanic Gardens Kew houses approximately 7 million specimens, collected from all around the world. Specimens are either pressed and dried or preserved in spirit. Kew is committed to making this important collection more accessible to botanists and others, wherever they may be, for use in their own projects: particularly in biodiversity, conservation, sustainable development and systematics. To this end we are building an electronic Herbarium Catalogue containing images of the specimens and information taken from their collection labels. ... [Information of the supplier]
A bibliography of over 200,000 publications published since 1971 and relating to the taxonomy of flowering plants, gymnosperms, and ferns. The Kew Record database contains references to all publications relating to the taxonomy of flowering plants, gymnosperms and ferns. It also includes references on phytogeography, nomenclature, chromosome surveys, chemotaxonomy, floras and botanical institutions, along with articles of taxonomic interest in the fields of anatomy and morphology, palynology, embryology and reproductive biology, and relevant bibliographies and biographies. ...

Carl Linnaeus (1707-1778) introduced the consistent use of binomial names for both plants and animals, validly publishing over 9,000 plant names. Since 1981 the Linnaean Plant Name Typification Project, based at The Natural History Museum, has been collating and cataloguing information on published type designations for Linnaean plant names and, where none exists, has been collaborating with specialists in designating appropriate types. A type specimen is one which is permanently associated with a given scientific name, and acts as a permanent reference collection to confirm the identity of the species to which the name must apply. The Project's main aim is to promote nomenclatural stability in Linnaean plant names by establishing clear typifications for each of the names involved. The Project is necessarily international in scope, receiving enquiries and requests for information on Linnaean names from all over the world. We are always keen to develop further collaboration with taxonomic or regional specialists in the evaluation of Linnaean names and their types. Based at The Natural History Museum, the Project is also indebted to the Linnean Society of London for generous grant support. ... [Information of the supplier]
The Linnean herbarium at the Swedish Museum of Natural History in Stockholm comprises some 4000 herbarium specimens, several of which are types formally designated by various experts. The specimens were once distributed by Linnaeus to his disciples and eventually they became part of the collections of the Royal Swedish Academy of Sciences, subsequently the Swedish Museum of Natural History. Linnaeus' main collections are today housed at the The Linnean Society of London. So far, this material has only been available to visiting scientists, and as small black and white microfiche photographs. Images of a number of specimens from the Linnean herbarium in Stockholm are now presented on the museum web-server. It is our ambition that the presentation will eventually include images of all the sheets in this Linnean collection. ... [Information of the supplier]
This site provides access to the Missouri Botanical Garden's VAST (VAScular Tropicos) nomenclatural database and associated authority files. Enter a scientific name in the box below to obtain current information on the name, its place of publication, type, and other information about the plant. Examples of name entries would be Poa, Olyra latifolia, Acacia baueri aspera. ... [Information of the supplier]
