Macaranga sp.

It should be Macaranga denticulata as per Checklist of Nepal (POWO treats Macaranga pustulata King ex Hook.f. as a syn. of it) as per

Macaranga denticulata and M. pustulata are entirely different species based on fruit characters according to Whitmore, Gen. Macaranga Prodr. (2008) and both the species are occurring in India.

What is the plant posted by …?

This is Macaranga pustulata.
1 image.

However it is still shown as syn of M. denticulata in POWO, WFO, CoL and GBIF.
So the accepted name should be Macaranga denticulata var. pustulata (King ex Hook.f.) Chakrab. & M.Gangop.  ??

Any article / journal on update on this sp. ??

This is a wrong concept advanced by me. If you go through the book Gen. Macaranga Prodr. by T. C. Whitmore (2008) he has shown that these two species are quite distinct. See the image attached by me. The fruits of M.  pustulata have glandular patches on the lobes which is absent in M. denticulata.

Need to look for the book !

This book was published by Kew. Please see Flora Malesiana Euphorbiaceae online and there you will get the treatment of both the species.
