During the first thirty years of Atlas Florae Europaeae (AFE), the basic technology for the collection of distribution data and publication of distribution maps has remained practically unchanged. Manual map production as such is rather tedious. Furthermore, distribution data available only on printed maps are not suitable for further (computerized) analyses. The construction of the Atlas Florae Europaeae database was started in 1992. The primary goal was to make the distribution data available in digital format, and the additional goal was the computerization of the editorial process of AFE. The printed AFE distribution maps were processed this way: - the maps were scanned at 300 dpi resolution / - locations of the grid cells (4419) were calculated on the scanned bitmap images / - arrays of black pixels were searched from the bitmaps using custom software / - the map originals and and their interpretation were compared using custom software. So far all printed AFE volumes (1 to 12) have been processed this way. ... [Information of the supplier]
Euro+Med PlantBase ("the information resource for euro-mediterranean plant diversity") provides an on-line database and information system for the vascular plants of Europe and the Mediterranean region, against an up-to-date and critically evaluated consensus taxonomic core of the species concerned. After several years of planning, the project is now firmly underway. The first stage of the project (referred to as Phase One) has been financed for three years by the European Union under Framework V. This database is constantly expanded and improved. Already in 2009, EuroMed provides three of the largest families: Compositae (Asteraceae, sunflower family) Poaceae (Gramineae, grass family) Rosaceae (rose family); and the following smaller families: Alismataceae, Aponogetonaceae, Basellaceae, Butomaceae, Cabombaceae, Chenopodiaceae (only tribus Salicornieae), Corylaceae, Elatinaceae, Geraniaceae, Haloragaceae, Hippuridacae, Hydrocharitaceae Juncaginaceae Lemnaceae Lilaeaceae Myricaceae Najadaceae, Nelumbonaceae, Nymphaeaceae, Posidoniaceae, Potamogetonaceae, Proteaceae, Ruppiaceae, Scheuchzeriaceae, Sparganiaceae, Tetragoniaceae, Zannichelliaceae, Zosteraceae, Zygophyllaceae. Common names were not yet available in all languages. By April 2015 Euro+Med Plantbase provided access to 190 plant families, corresponding to ca. 95 % of the European flora of vascular plants. ...

HOSTS brings together an enormous body of information on what the world's butterfly and moth (Lepidoptera) caterpillars eat. The web-based version presented here offers a synoptic data set drawn from about 180,000 records comprising taxonomically 'cleaned' hostplant data for about 22,000 Lepidoptera species drawn from about 1600 published and manuscript sources. It is not (and cannot be) exhaustive, but it is probably the best and most comprehensive compilation of hostplant data available. ... [Information of the supplier]
The Index Nominum Genericorum (ING), a collaborative project of the International Association for Plant Taxonomy (IAPT) and the Smithsonian Institution, was initiated in 1954 as a compilation of generic names published for all organisms covered by the International Code of Botanical Nomenclature. (...) The original intent of the ING was to bring all generic names of plants together in a single list to reveal homonymy between groups. In addition, ING includes bibliographic citations and information about the typification and nomenclatural status of generic names. ... [Information of the supplier, modified]
The Index to Plant Chromosome Numbers is an NSF funded project that aims to extract and index original plant chromosome numbers of naturally occurring and cultivated plants published throughout the world. A committee of voluntary contributing editors, located in various parts of the world, reviews sets of serial titles assigned to them and returns the information to the editors for collation in the Index. Chromosome indexes are published every two years. The Index to Plant Chromosome Numbers project has been based at the Missouri Botanical Garden since 1978. Data from published indexes from 1984 onward are available for consultation through this facility. ... [Information of the supplier]
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. IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium. ... [Information of the supplier]
The DNA amount in the unreplicated gametic nucleus of an organism is referred to as its C-value, irrespective of the ploidy level of the taxon. The Plant DNA C-values Database currently contains data for 3927 different Embryophyte plant species. It combines data from the Angiosperm DNA C-values Database (release 4.0, Jan. 2003), the Pteridophyte DNA C-values Database (release 2.0, Jan. 2003 ) together with the Gymnosperm DNA C-values Database (release 2.0, Jan. 2003) and the Bryophyte DNA C-values Database (release 1.1, Jan. 2003). ...
