The Euphorbia taxonomy database is available through TOLKIN and it can be accessed using any internet browser except Internet Explorer at http://app.tolkin.org/projects/72/taxa

The Euphorbia database can be searched by any of the available fields (Filters). Select one or more filters and enter your searching criteria, and then click on "Search". For example, filtering by Subgenus (Esula) and General Distribution (U.S.A.) will give you all the species of subgenus Esula occurring in the United States, including introduced species. Clicking on any of the resulting records will take you to a given species web page with all the information, if complete, about nomenclature, distribution, images, description, literature, etc.

This is a work in progress and there are many species still lacking formal descriptions, but new information will be added as we continue populating the taxonomy database with new descriptions, images, specimens, and other relevant information about individual species.
