- DELTA (DEscription Language for TAxonomy)
The DELTA format (DEscription Language for TAxonomy)
is a flexible method for encoding taxonomic descriptions for computer processing. It has been adopted by the International Taxonomic Databases Working Group (TDWG) as a standard for data exchange. DELTA-format data can be used to produce natural-language descriptions, conventional or interactive keys, cladistic or phenetic classifications, and information-retrieval systems. - Den virtuella floranSwedish Natural History Museum; in Swedish.

- Digital Natural History of Newfoundland and LabradorThe website is a co-operative project/partnership, involving a number of individual participants, some representing present or former parent institutions or agencies, others representing themselves. The website was begun, originally, to serve as a working image resource for the Newfoundland Rare Plant Project. It is hosted by one of its main partners, the The Rooms, Provincial Museum. Rights to the images and data included remain with the various individual partners.
- Flora Danica OnlineThe digitizing of Flora Danica is part of a CultureNet Denmark project carried out at The Danish National Library of Science and Medicine (DNLB). The purpose of the project is to publish Danish plates of natural history on the WWW. All 3240 plates are available on the WWW. It is posssible to search individual plants and to browse the plates.
- Flora of IcelandIt is not known exactly how many plants in the widest sense, are involved in the Flora of Iceland. A team of Icelandic scientists, especially at the Icelandic Institute of Natural History, are investigating the different groups of plants, and they find every year several species not known from Iceland before, especially fungi, lichens and bryophytes. The phanerogam flora, flowering plants and ferns, are far better known. Only exceptionally, or once every 10 years are new wild species of vascular plants discovered in Iceland. One of the last one was Andromeda polifolia, which grows in a few remote places in the Northeastern part of the island. As far as known today, there are more than 5.000 species of plants and fungi growing wild in Iceland.

- Lichen Herbarium – University of Oslo, NorwayThe lichen herbarium at the Botanical Museum in Oslo consists of a Norwegian herbarium (c. 100,000 specimens), a foreign herbarium (c. 170,000 specimens), a type herbarium (c. 1,000 specimens), and a collection of exsiccatae (c. 5,000 specimens).The herbarium maintains a database of species housed in our Norwegian and foreign herbaria, a checklist of the Norwegian lichens, and the list of Norwegian vernacular names for lichens proposed by the Norwegian Botanical Society. These lists may be downloaded from our Up-/Download page.
- Linnean Herbarium – Swedish Museum of Natural HistoryThe 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.

- Robert W. Freckmann Herbarium – University of WisconsinThis website attempts to present information to the botanists and general public about the plants growing in Wisconsin. The site is divided into several areas. Natural Communities, Ethnobotany, Vascular Plants, Bryophytes, and Lichens. Each Species Detail page has, when available: a thumbnail map, photograph, synonym list, descriptions of the plant including status, size, flower, stem, leaf, fruit, blooming times, botanical name derivation, and links to ethobotanical uses, additional photographs, natural community information, detail distribution maps, direct links for more information, and Google searches.

- Plants of IcelandThis site deals with the birds, plants, and landscape of Iceland. It offers photographic guides to characteristic floral elements, birdlife, and landscape images of this remarkable island: in the top menu choose "entries start". Next to the photo-illustrated guides, in-depth information on vegetation, bird life and geology is presented in the "birds/plants information pages" and the "landscape features of Iceland". Also two internal search programs are included through which you can search directly for information on specific plants or birds.
