Unfortunately, the plant species are the weakest part of this site. There are nonetheless world links to many sites where plants are listed. Constructed and maintained by Envirolink. The major focus of the site is research, crop information, cooperative extension information and publications. Methods of controlling pests and the scientific approach to growing better plants are emphasized here.
Some material is for sale, but much of it is online here.
Developed in cooperation with the University of California, Davis, Riverside and Berkeley. The interface is not obvious but the results provoke thought. Site hosted by Cornell University, based on current research being done by scientists at the Boyce Thompson Institute for Plant Research. The site hosts mailing lists, interest groups and extensive tutorials from this site. If you are interested in learning about web resources or describing them to others, this site deserves a bookmark.
