Herbariorum, hosted by the New York Botanical Garden, is a
detailed directory of the 3000+ public herbaria of the world
including staff members associated with it. The electronic
searchable version includes up-to-date information on 2010
herbaria in 134 countries.
by Christopher J. Earle. This database has descriptions of
1000+ taxa of gymnosperms, i.e., conifers, cycads, and their
allies. This database provides entry at the family level and
guides to genus, species and sometimes variety for each taxon.
Basic information on each species generally includes a picture,
a distribution map, common names, taxonomic notes, description,
range, "big tree", oldest, dendrochronology, ethnobotany,
remarks, and citations.

of the database proceeds simultaneously with the preparation
of the hard-copy flora. The database will eventually contain
all the information found in the published volumes as well
as additional information, such as more detailed morphological
data, information on type specimens, and documentation for
chromosome counts. It will also incorporate information on
habitats, precise distributions, populations, and plant communities.
is a source for authoritative conservation information on
more than 50,000 plants, animals, and ecological communities
of the United States and Canada. NatureServe provides in-depth
information on rare and endangered species, but includes common
plants and animals too. NatureServe is a product of the Association
for Biodiversity Information in collaboration with the
Natural Heritage Network.
PLANTS Database is a single source of standardized information
about plants. This database focuses on vascular plants, mosses,
liverworts, hornworts, and lichens of the U.S. and its territories.
The PLANTS Database includes names, checklists, automated
tools, identification information, species abstracts, distributional
data, crop information, plant symbols, plant growth data,
plant materials information, plant links, references, and
other plant information.
trees guide: http://osu.orst.edu/instruct/for241/dk/start.html
by the College of Forestry, Oregon State University. Includes
pages on What is a genus, a dichotomous key taken from an
OSU extension service publication, a list of 15 common trees
of the NW with a short description and small picture. This
is linked to a species page with four pictures (foliage, size
of leaf, bark, and distribution map. The last feature is a
mystery tree identification to encourage folks to use the
key for genus description, a nice feature.
trees of Ohio: http://www.oplin.lib.oh.us/products/tree/
by the Ohio Public Library Information Network and the Ohio
Historical Society. Uses two parts of the tree -- the leaf
and fruit -- to identify the common trees of Ohio. A bibliography
of reference works and keys is also provided. From an alphabetical
list of tree names, dual pictures of the leaf and the fruit
with a list of characteristics are shown. The tree and its
scientific name plus something about it (history, growth habits)
with pictures of the bark, a twig and a branch are provided.
trees of Iowa: http://www.exnet.iastate.edu/Pages/tree/
by the Iowa State University Extension. Includes a tree identification
key, an index of Iowa trees linked to a page with small pictures
and description, a definition of a few leaf and fruit terms
with diagrams, descriptions of how a tree grows (roots, trunk,
crown, and tree form), and a paper on the history of Iowa's
trees of Pennsylvania: http://www.dcnr.state.pa.us/forestry/commontr/common.htm
by the Department of Conservation and Natural Resources. This
selection of 57 native, and 5 introduced trees is organized
according to leaf shape and arrangement. Each tree is identified
by popular name familiar to Pennsylvanians and its complete
trees in Eastern and Central US: http://www.treelink.org/whattree/index.htm
National Arbor Day Foundation, c1998. Found on the TreeLink site, a site
intended for "people working in urban and community forestry."

eastern pines. Emphasis is placed on woody species native
or naturalized in eastern North America

Identification of a tree by following any of six possible paths:
or the overall growth pattern of the tree. Each topic
is simply described and illustrated with large and beautiful
examples. Very nice site for elementary school students
a Tree: http://www.ag.iastate.edu/departments/forestry/ext/adoptree.html
great way to allow children the opportunity to learn about
plants such as trees is to have them actually adopt a tree
or group of trees and keep a "tree log" or diary with information
about their adopted tree or trees. This site gives details
on how to do this.
