The Euphorbia genus was named and described by Carl von Linnaeus in Species Plantarum in 1753.
Euphorbia is a very diverse genus of flowering plants in the plant family Euphorbiaceae commonly known as the spurge family.
Plants of the World Online lists 1,990 accepted species of Euphorbia (as of 1/23/21 when I updated this page).
There is a lot of useful information online about many genera and species in this family. I am not going to do an extensive write up at this time, but the following links are a good place for you to start. The links take you directly to the information on the genus Euphorbia.
If you have any comments, questions or suggestions, I would like to hear from you. You can leave a comment about the error or email me at firstname.lastname@example.org.

NOTE: WORLD FLORA ONLINE uploaded out-of-date data from the Plant List (unmaintained since version 1.1 in 2013) so all information on that site is not up to snuff… Thousands of accepted species names have changed and reclassified since 2013… They are supposed to upload up-to-date data from World Flora Online, but at the time I was updating this page on 1-23-21 it still hasn’t happened…
