For years our research group has been involved in several projects regarding the identification of plant organisms, using the DNA barcoding. The necessity of these studies arose both from purely systematic questions and on behalf of privates or public institutions. The organisms considered in our researches range from cyanobacteria and microalgae to seaweeds and, only recently, plants. One of the major problems in our studies was the availability of molecular data from type and historical specimens. In fact, type specimens are fundamental for comparison in systematic and nomenclature studies, as stated by the International Code of Botanical Nomenclature, and, more in general, specimens from historical collections are useful to know the distribution of taxa in space and time. DNA barcoding technique has allowed us to study historical specimens of great scientific value, because only small amount of starting material is required, thus preserving these irreplaceable sources of information. We have decided to make available to everyone the sequences of type and historical material produced during our researches in this public database. It will represent a library of reference sequences, easily to update and against which putative new species or other plant material can be compared. A match of a sequence from an unknown organism to one of the reference sequences can provide a rapid and reproducible identification. This will greatly increase the speed at which routine identification can be carried out and will be a good tool to solve taxonomic questions, inferring evolutionary history and determining chronological distributions of populations. ...

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]
Botany is the scientific study of plants and fungi. Scientists in the Department of Botany at The Field Museum are interested in learning why there are so many different plants and fungi in the world, how this diversity is distributed across the globe and how best to classify it, and what important roles these organisms play in the environment and in human cultures. ...

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 merges the book A Guide to Field Guides: Identifying the Natural History of North America by Diane Schmidt, Biology Librarian at the University of Illinois, and its companion Web site International Field Guides. After the publisher returned copyright to the book, the author decided to combine the two products and create a searchable database of field guides for plants, animals, and other objects in North America and around the world. Except where noted, all guides listed here were personally examined by the author. As used in this site, a field guide is a small, lightweight book used to identify plants, animals, or other objects. It is designed to be used outdoors and usually contains many illustrations, whether drawings or photographs, and limited text. Generally speaking, field guides are used by amateurs, hence the emphasis on visual identification. There are a number of different technical manuals, atlases, floras and faunas, handbooks, and keys for the use of professionals which are not listed here. ... [Information of the supplier]
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]
JSTOR Plant Science is an online environment that brings together content, tools, and people interested in plant science. It provides access to foundational content vital to plant science – plant type specimens, taxonomic structures, scientific literature, and related materials, making them widely accessible to the plant science community as well as to researchers in other fields and to the public. It also provides an easy to use interface with powerful functionality that supports research and teaching, including the ability to measure and record plant specimens, share observations and objects with colleagues and classmates, and investigate global plant biodiversity. JSTOR Plant Science strives to be a comprehensive online research tool for aggregating and exploring the world’s botanical resources, thereby dramatically improving access for students, scholars, and scientists around the globe. It is useful for those researching, teaching or studying botany, biology, ecology, environmental and conservation studies. ... [Information of the supplier]
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]
