Here is the euphorbia. Small trunk with 4 sides.

Could you perhaps take a close up of the thorns and the rib edges? When it comes to these kinds of euphorbia,every detail helps....

Stefan, will do it to night.

Thanks

Stefan, hope these images help.

Thanks

yc, there's a wonderful Euphorbia compendium (though it has not been updated in years - I wonder what happened to Frank?) with names and pics. Maybe yours is in there. You can spend a lot of time looking at nice plants, that's for sure.

Stefan and cactusmcharris, many thanks for your help. I will check the site
