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.

Macaranga denticulata (Blume) Müll.Arg. ??

yes. looks like it. other name in FOI is Blistery macaranga

of course its ultimately an Euphorbiaceae via a long route:

Family:  Euphorbiaceae>>   Subfamily:      Acalyphoideae >> Tribe: Acalypheae >> Subtribe: Macaranginae  >>Genus: Macaranga  Thouars 1806[1] per wikipedia

no wonder its sap is not  innocuous

i have seen in thailand on streets

The name is Macaranga denticulata (Blume) Müll.Arg. var. pustulata (King ex Hook.f.) Chakrab. & M.Gangop. distributed in India (Uttarakhand,  West Bengal, Sikkim, Arunachal Pradesh, Meghalaya, Assam and Nagaland), Nepal, Bhutan, Bangladesh, Myanmar and China in subtropical evergreen forests, chiefly in old forest clearings, on landslips and abandoned plantations, beween 600 – 2000 m altitudes. 

Thank you … There is still some confusion for me.

Confusion according to the links about the correct ID !

Please forget about the links. I reduced Macaranga pustulata to a variety of M . denticulata as it is less pubescent and there will be a few black spots or pustules at the base of lamina where it meets with the petiole.

Is this not Macaranga pustulata?

I have no idea

What is the difference between the two?

Here in case of Macaranga pustulata, there are conspicuous glandular patches/pads on the lobes of ovary and fruits which are lacking in M. denticulata.

Please look here: glandular patches in M. pustulata. Moreover, there will be black dots on leaf lamina near the junction of petiole.

So you mean to say that it is M. pustulata as there are black dots on leaf lamina near the junction of petiole.
Is it?

Fruit character is distinctive between the two species.

But we can not see the fruit character here.
So what do you finally consider it to be ?

Macaranga pustulata.

I think Macaranga sp.

I am just giving a suggestion and you need not take it for granted and you must verify this yourself before posting in Facebook … My suggestion: Macaranga denticulata.

Could it be Macaranga indica Wight ??

This is not Macaranga indica as the fruits are not 1-locular but clearly 2-locular in the images.
This is Macaranga denticulata (Blume) Müll. Arg. var. denticulatea.

Is it different from Macaranga denticulata (Blume) Mull. Arg. ??

No …, This is typical M. denticulata very abundant in that area. Leaves are epeltate as well as slightly peltate, as in these images. Good images are available in efi website. Var. pustulata is slightly different in less deep lobes of fruits and less pubescens with etimes a few pustules near the base of the leaves. M. indica is very different in 1-locular fruits and with a large gland at the base of the bracts outside and it is rather rare species.

Can it also be Macaranga pustulata?

Yes, Macaranga pustulata.
