Euphorbia echinus at the BBC Show in Maharashtra Nature Park, Mumbai.
For id confirmation.

I think the identity is correct. In that case, the correct name should be Euphorbia officinarum subsp. echinus (Hook.f. & Coss.) Vindt [syn.: Euphorbia echinus Hook.f. & Coss.]

euphorbia sps

Yes … This is Euphorbia species
Difference between Euphorbia and Cactus are as follows
The spines in a cactus are many and come from a circular area called aerole.
In Euphorbia there is no aerole and spines are only 2[modified stipules]
Euphorbia has white latex, cactus generally has transparent sap. All cacti are exotic, they come from America. Many Euphorbia species are indigenous [eg E.nerifolia, E.lactea…..]
In catus the flower is solitary [usually big and showy].
In euphobia it is a group of tiny flowers.. flower head.. male and female separate lacking petals [Chyme inflorescence]

This appears to be the same as at Euphorbia officinarum subsp. echinus (Hook.f. & Coss.) Vindt

Yes appears to be the same.
