I want to know if there is any other registered scientific name for my plant, how and where can I find synonyms of my plant? Especially with same genus and different species.
I agree with "Alessandro Venditti", I have also found two synonym for your plant and that is "Tithymalus erythradenius and Euphorbia heteradena". For more detail you can follow the link: http://profdoc.um.ac.ir/articles/a/1025048.pdf
