I never see it in indonesia, maybe a full photo of this plant can make us easier to help :) , root, stem, leaf, (fruit optional)

Where is it from? Try Oleaceae, possibly Jasminum.

That´s great. really thanks adriaan. :-)

What's the geographical source? I believe its from Oleaceae but leaves differ from Jasmine. A full picture of the plant can help in this case.

I found it, is Jasminum polyanthum, was very simple like to have a mouse in the point of my nose, thank you very much, I have found it in colombia south america, I´m making a research about weeds but this flower capture my attention by the sweet smell.

You are very welcome. The plant parts in your photo seem to fit the description for J. polyanthum. It sounds like quite an aggressive invader! Are you investigating chemical control of these weeds?

Oleaceae, Jasminum species
