Euphorbia leucocephala L. photographed from Panchkula Cactus garden.
I do not think your photograph belongs to E. leucocephala. I have copied Dave's Garden website, a photograph of the true E. leucocephala. Please note that the leaves surrounding the cyathia (so-called floral leaves) are smaller and completely white. In your specimens the cyathia are usually solitary and without any white floral leaves. The white structures are limbs of glands.
Your photograph do not fit into any Indian species. May be an introduced one.
I just found this photograph on the website of University of Florida very much resembling mine. Please have a look and give your verdict.
