Sites with Nomenclatural Information
International Plant Nomenclatural Index IPNI: http://www.ipni.org/index.html
IPNI combines three indices of plant names into a searchable database. Searches can be done by taxon or
by authority, including authority abbreviations. Citations for a scientific name provide a list of references.
Each reference will include complete author details and the citation for where the taxon was published.
These lists are not ranked for acceptance or validity. Searches by authority return the complete name,
standard abbreviation, birth and death dates, and home country.
Tropicos is developed and maintained by the Missouri Botanical Garden. A multifaceted site, the data portal
features of Tropicos are covered separately in Global Data Portals. In addition to searchable specimen
information, Tropicos is also useful as a source of nomenclatural information. Searching for a taxon returns a
list of names containing that taxon (so if you search for a species Tropicos will return a list that also includes
all of the subspecies). Unlike INPI, Tropicos also includes nomenclatural evaluations, and will mark names in
the list as legitimate, illegitimate, invalid, nom. rej., or nom. cons. Clicking on a taxon produces the
authorities, publication source, birth and death dates, and home country, as well as basionyms.
The USDA Plants database: http://plants.usda.gov/java/ attempts to cover all vascular plant species found
in North America. More aggressive than Tropicos, this site clearly chooses a preferred name for each taxon,
and lists other taxa as synonyms. The correct authority is given in abbreviated form. The taxon namepage
also includes a distribution map that can be expanded to show counties of distribution within a state, and
images of the taxon.
eFloras is a comprehensive on-line compilation of digitized floras of the world. Search for a taxon, and it will
returns a floristic treatment of the taxon from one of the available floras. Complete citation, species
description, a distribution map, and links to other relevant sites are all displayed.
Sites with Herbarium Data Tools:
The Index Herbariorum: http://sciweb.nybg.org/science2/IndexHerbariorum.asp
The Index is a compilation of herbaria worldwide. Continuously updated, the Index is searchable by a variety
of fields (institution, location, personnel name, etc.). Registered herbaria are given a unique letter code, and
curator, contact information, herbarium website, and basic information about the collection are presented.
The Index is also a good way to search for people if you don't know which institution they are associated with.
Sites with Floristic Information
GEOLocate is a set of software tools that can be used to locate and calculate GPS coordinates for
any particular spot in the United States. A standalone desktop client can be downloaded, and
GEOLocate has also been incorporated into Specify. A very powerful useful tool.
Sites with Institutional Information
Specify is an NSF-supported free software package for managing a database of museum specimens.
There is considerable help available to troubleshoot issues, which is important because it is not a
simple package to learn or employ. However, a number of herbaria have chosen to manage their data
Harvard Index of Botanists: http://kiki.huh.harvard.edu/databases/
Enter the name of a collector, curator, or identifier. A list of matching names will be produced. Pick a name
from the list to learn more about the individual.
A product of the iPlant collaboration, TNRS 3.0 attempts to resolve issues associated with nomenclature. A
taxon can be searched, and TNRS will consult the Global Composites Collection, Tropicos, and the USDA
plants database, and return an evaluation of the authority associated with the taxon. Authorities may be
accepted, rejected, or a list of possible correct citations will be presented. One of the nice features of TNRS
is that it can be operated in batch mode. Thousands of taxa can be submitted in batch mode, and a file will
be built with the opinions of TNRS
This is an exciting new site, but the results should not be blindly accepted. For a full review of TNRS, see the
upcoming issue of the Wired Herbarium in the publication list.
Sites with Information about Botanists:

Garden. Enter a publication, and the search engine will attempt to find it. Downloadable pdfs can be
