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]
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. ...

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). ...

The plant snoRNA Database and web-site brings together information from three independent computer-assisted searches of the Arabidopsis genome for box C/D snoRNA genes and from studies of ncRNAs. To date, the Arabidopsis box C/D snoRNAs have been used to identify approximately 250 genes from different non-Arabidopsis plant species and these sequences are included as alignments in the Database. Finally, the Database provides a unifying nomenclature for all of the plant snoRNA genes. ... [Information of the supplier]
The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references. This information primarily promotes land conservation in the United States and its territories, but academic, educational, and general use is encouraged. PLANTS reduces government spending by minimizing duplication and making information exchange possible across agencies and disciplines. PLANTS is a collaborative effort of the USDA NRCS National Plant Data Center (NPDC), the USDA NRCS Information Technology Center (ITC), The USDA National Information Technology Center (NITC), and many other partners. Much of the PLANTS data and design is developed at NPDC, and the Web application is programmed at ITC and NITC and served through the USDA Web Farm. ... [Information of the supplier]

This series of pages is a set of characterizations of all orders and families of extant angiosperms (flowering plants) and gymnosperms, i.e. all seed plants, as well as many clades grouping families and orders and some smaller clades, especially within larger families. They are designed to help in teaching seed plant phylogeny at a time when our knowledge of the major clades of seed plants and the relationships within and between them are still somewhat in a state of flux, even if much of the broad outline is becoming clear. Here I very largely follow the Angiosperm Phylogeny Group classification (APG 1999, 2003), although with one or two more orders and with a number of unplaced families in slightly more resolved positions in the tree - recent examples are Hydatellaceae, Perrottetia and Bhesa (Zhang & Simmons 2006). ...

The Kew Bibliographic Databases is a combined searching tool giving you access to three bibliographic databases: KR - The Kew Record of Taxonomic Literature (over 200,000 publications relating to the taxonomy of flowering plants, gymnosperms and ferns from 1971 onward), PMBD - the Plant Micromorphological Bibliographic Database (over 90,000 references to publications and is probably the most comprehensive computerised index to higher plant micromorphology in existence) and EBBD - the Economic Botany Bibliographic Database (33,000 references to publications relating to the uses by humans of flowering plants, gymnosperms and ferns). There is no charge for using the KBD and you may carry out a simple search, retrieving a limited number of references, without registering. Registered users can access a much larger number of records at a time, search just the data sets they are interested in, download selected records, save searches for repeated use and perform more complex searches. ...
