Hi, I found a website who mentioned that Opuntia Canterae and O. Elata are the same

This is the close-up of the Opuntia, and Euphorbia Globosa, the Globosa has the pattern like turtle skin.

Side by side
Btw, I have problem to keep the shape of this E. Globosa, the plant like to grow a thin and long stem for flowers, and after flowering, the end of the branches will grow a new segment of the turtle, make it top heavy and can not stand without support. Maybe I should prune all of those thin stems after flowering.
