Note the conspicuous glands at the base of leaves and petioles inserted slightly above the base of the leaves.  As regards the varietal name, this appears to be the less pubescent var. pustulata but we can be sure of this only if the fruits are made available which will not be deeply bilobed as in var. denticulata and there will be a large viscidly glandular patch on the back of the cocci.

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.

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.
