Dear Saroj ji

Yes this is Euphorbia sikkimensis Boiss., characterised by the solitary terminal cyathium within the 3 pseudoumbel leaves.

Yes, this appears close to E.sikkimensis but have you considered Euphorbia schillingii?  There is a photo in the 'Supplement' to 'Flowers of the Himalaya'

(which was privately published & paid for by the late Adam Stainton, co-author of the main 'Flowers of the Himalaya') which was named provisionally as

Euphorbia aff. sikkimensis - meaning "has affinities to", which comes very close to the specimen at Kalinchowk.  I did once ask a member of staff at Kew their precise interpretation/usage of the term but never got a reply.  Like so much, there is an element of interpretation involved.

Anyhow, in the description Stainton states, "the plant illustrated was photographed by Mr. A.Schilling in the Dudh Kosi valley of E.Nepal... it differs in

some respects from E.sikkimensis".  At the end of the introduction to this book, the author noted (1997) that the specimen was about to be published as a new species, Euphorbia schillingii (please note Schilling was from the UK Royal Horticultural Society and helped establish The Royal Botanic Garden, Godawari, Nepal) A.Radcliffe-Smith.  A principal distinction is that the fruits are warty, whereas the fruits of E.sikkimensis are smooth.  Saroj's images are of immature fruits but I think I can detect developing warts?  What do others think.

E.schillingii has been recorded from Central & East Nepal.  E.sikkimensis has been recorded from East Nepal to Bhutan and Tibet.  But perhaps the distribution of both are not perfectly know due to similarities.  There are herbarium specimens labelled as E.sikkimensis collected by Hooker in India at Kew which can be viewed on-line.

Euphorbia is a big and difficult genus to me.
What I am able to see in the plate of 'Flowers of the Himalaya: A supplement' (by A.Stainton) and referred by Chadwell Ji, that the cyathia are terminal but not solitary as the cyathia are surrounded by few bud like structures (E. schillingii). Such structures are not visible in the images by Saroj Ji. The specimens at Kew have little help as detailed structure can not be seen in them and the type of species are from the plant cultivated in Europe.
