Just thought I clarify -
I found two of my images entered as Euphorbia tortirama
I tried to move only those two images to Euphorbia persistens which is renamed to E. clavigera. (Thanks for correcting the species) I guess I had mistakenly asked to merge the two species, sorry.
All images of mine on either so called tortirama or clavigera are of the same plant. I always thought them to be persistens/clavigera. The growth on persisents is fairly straight while tortirama is more twisted.
If I am incorrect, please ignore it.
Thanks
