Taxa not yet added to section Monadenium in iNaturalist. To graft these, I recommend taxonomic view so you can see if anyone has added them to the section already. The best way I've found to actually change them is to open each species in a new tab and manually change them (let me know if there is a better way).

Taxa not yet added at all as follows (1):
Euphorbia major
