Euphorbia For ID : Lalbagh,Bangalore : 301113 : AK-1 : Attachments (3). 5 posts by 3 authors.

An ornamental Euphorbia seen at Lalbagh a week ago.

On searching, it looks close to Euphorbia grandialata to me.
Kindly validate.

Euphorbia cooperi I hope

In another thread I suggested that this could be E. opuntioides.
However, now I find that this could be Euphorbia quadrialata R.A.Dyer. I am reproducing a photograph from the website of Cactus King.

To me it does not look like E. quadrialata, in which stems are not candelabra-like clearly seen above

To me looks much more nearer to E. cooperi

Could this be Euphorbia grandialata?

Dragon Fish Bone Cactus Plant?
Just a guess.

I still believe that this is Euphorbia quadrialata R.A.Dyer, not grandialata! It is also not E. cooperi

Thanks for your feedback and identification of my Euphorbia from Lalbagh.
