PPI's working papers, produced from 1992-2004, are a series of 13 case studies on significant themes in applied ethnobotany. Most titles are accessible below in PDF format. The People and Plants Handbook series started in 1996 to provide an accessible information source on ethnobotany, conservation and development, and to enable ethnobotanists and others in developing countries to be in touch with one another and with a wider global network.
PERIODIC is a bibliographic database created in 1978 at the National Autonomous University of Mexico (UNAM). The database is updated daily and more than 10,000 records are added each year. It offers about 350 000 bibliographic records of original articles, technical reports, case studies, statistics and other documents published in about 1500 journals from Latin America and the Caribbean, specializing in science and technology.
Persée is a program which was created for the digital publication of scientific journals in the field of the humanities. The entire printed collection of journals is digitized and published online through a portal which offers access to the collections as well as advanced functionalities which facilitate and enhance use of the portal’s resources. The French journals in the field of humanities constitute a rich scientific heritage. Their digitization and online publication aim to fulfill a triple objective: promote scientific publications in French; facilitate free access to the results of scientific research; furnish the scientific community with tools for research and documentation.
PHYLIP is a free package of programs for inferring phylogenies. It is distributed as source code, documentation files, and a number of different types of executables.
Phytozome is the Plant Comparative Genomics portal of the Department of Energy's Joint Genome Institute. Families of related genes representing the modern descendants of ancestral genes are constructed at key phylogenetic nodes. These families allow easy access to clade-specific orthology/paralogy relationships as well as insights into clade-specific novelties and expansions. As of release v10, Phytozome provides access to forty-eight sequenced and annotated green plant genomes which have been clustered into gene families at 12 evolutionarily significant nodes.
Based on available science, the plants recommended here were found in this region prior to the arrival of the colonists at Jamestown, thus making them native plants. A panel of local experts chose these plants based on their current or potential availability, their overall aesthetic interest, and their likelihood to grow well without major care.
The Pioneers of American Landscape Design® initiative chronicles the lives and careers of those who have designed our gardens, parks, streets, campuses, cemeteries, suburbs, and the innumerable other environments in which we live. This dynamic, ongoing series utilizes multiple formats—including biographical profiles, videotaped and transcribed oral histories, tours, and print publications—to educate, inspire, and promote the active sharing of information.

Plant Information Online offers a collection of databases of interest to plant and gardening enthusiasts and students, as well as professional botanists, horticulturists, and researchers.
The Plant List is a working list of all known plant species. It aims to be comprehensive for species of Vascular plant (flowering plants, conifers, ferns and their allies) and of Bryophytes (mosses and liverworts). The Plant List includes 1,040,426 scientific plant names of species rank. Of these 298,900 are accepted species names. The Plant List contains 620 plant families and 16,167 plant genera.
The PO is organized in a complex hierarchical structure in which botanical concepts are described by their precise logical definitions and their relationships to one another.
Locate rare and threatened plant species in cultivation around the world using our unique PlantSearch database.
PlantCollections is an international partnership of botanic gardens, arboreta, universities, governmental funding agencies and commercial database software developers providing public access to information stored within plant record databases.
People who are Plant Explorers are different from those who are plant hunters, in that their goal is discovery more than acquisition. Plant Explorers today are often botanists or botanical photographers and painters, but can be anyone with a real love for nature and plants. If you are a Plant Explorer, or just someone who loves plants, then this site is for you.
The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.
A "Millennium Audit" of the vegetation of the Hull city area, United Kingdom. The audit has been regarded as that of a botanical "audit" with a view to assessing the biodiversity of the city.
Plants of southern Africa: an online checklist provides access to plant names and floristic details for southern African plant species.
a "plug-and-play" management and server solution for biodiversity data, with tools for image database management and retrieval, morphological data management, diagnostic key generation, cladogram display and navigation, specimen data, descriptions, classifications and nomenclature.

Open-access articles on the broad theme of biodiversity are selected and imported into the Hub.
Portraits of naturalists culled from the BHL database and posted to Pintrest
A collaborative project aiming to use a meta-analytic approach to investigate how local biodiversity typically responds to human pressures such as land-use change, pollution, invasive species and infrastructure, and ultimately improve our ability to predict future biodiversity changes.
promotes and shares peer-reviewed instructional materials created by librarians to teach people about discovering, accessing and evaluating information in networked environments.
