Yes indeed it is  Euphorbia caducifolia Haines. This was also the missing one from the panaroma posted so far ! Thanks. Some keys

 

A pale green, dense, fleshy, dendroid shrub , upto 2 m high, with numerous branches arising from the very base. -Aima's book pg 194.

 

Branches angular; stipular spines on prominent tubercles arranged in  spirals; leaves obovate or lanceolate; cyathia red- Dr. Almeida's flora , Vol IV-B, pg ; 304.      

The milky juice is used for colds  and applied for blisters on the skin The leaves are eaten and rarely sold in the market as a vegatable. -Aima -pg 194.

 

regards,

Rashida.

Attaching the type specimen. Keeping the size larger than normal so that the sketches are seen.

Rashida.

I doubt Samir ji's plant being E. caducifolia. This can be verified from careful comparison with type specimen attached by Rashida ji and the following links

E. caducifolia is more like E. nivulia in stem without angles, differentiated from latter in absence of distinct trunk with branches arising from base, smaller leaves (3-8 cm long) and longer spines 0.5-1 cm (leaves 10-25 cm long, spines shorter than 0.5 cm in E. nivulia).

To me the above plants appears E. neriifolia with spirally arranged spines on low angles.
