ID Please

I have just bought a few of these. Are they related to medusa head? What are they? Jkw

My first instinct is to say it is not one of the medusoids as i cant recall any in that group growing so upright, or branching midway along the stem. That said, these could be branch CUTTINGS of caput-medusae, as plants propagated that way do not produce a caudex to give it that symmetrical look. Still, the secondary branching is throwing me off. Other names like filiflora, loricata, and monteiroi come to mind, but for one reason or another don't feel right. Two things that would help id these are the width of the stems and 'flower' color.

Thanks for your response. I do believe the upright growth has to do with the fact they are cuttings. I have also heard that these medusa head euphorbias never form a natural caudex from cuttings, unless you try and invent it. I will try and use the formula from this video below to experiment. Have look at this video. But I must state I have a lot of doubts about the plant, and I have not had any other ID which seemed believable. Jkw

Never saw that video before but yes, that's a good demonstration of the 2 stage process you have to use to form 'heads'...basically cut, root, cut off tips, wait for new growth with heads formed,then cut those off and root them. Bonsai people love all the action! :-)
One thing though, the guy in the video should be wearing gloves. the milky sap is caustic and some sp like E.ferox for example will blister the skin so be careful when you're cutting!
