Where is it growing? Time of year would help, too....

Sassafras possibly.

if it is in tropics, it will remind me of cecropia seedling.

Thank you all for the responses. Yes, it is growing right now (the pictures were taken a couple of days ago) in the tropics, Indonesia to be exact. Did a quick search of both sassafras and cecropia, some characteristics fit both plants. Will do more research on this, could be interesting.. :)

Two good suggestions above.... If Sassafras, the leaves will be fragrant with rubbed or crushed.

Are the leaves attached to that bulging, shiny green root alongside?

I don't find sassafras leaves fragrant. I chew them and they make a gelatinous substance, but not particularly fragrant. Maybe that's the root?

Floral, no, that is Adenium root. This plant grow voluntarily in its pot (the Adenium is outside and has been neglected for several years..). Most likely the birds dropped it there.

Will check if the leaves have fragrance asap.

Thanks again for the inputs, really appreciate it.

it does not look like sassafrass ...

leaves of such.. when crushed.. rolled in your hand ... have a very MOMENTARY smell ...

may very first impression was poison ivy ... but i ruled it out fast ... but i caution you of putting things you dont know.. in your mouth.. until after ID ...

ken

Apparently there are two Asian species of Sassafras though neither is in the location of the OP. China and Taiwan each have a species, Sassafras tzumu and Sassafras randaiense.

tofrizal - are there any Breadfruit trees nearby?

Looks a bit like paper mulberry to me.

floral_uk z.8/9 SW UK- I was lived in Indonesia, now studying in Japan, in Indonesia I grow many arthocarpus sp, including the common breadfruit why?

I still stick that this is cecropia, the stem is large even for so young seedling, and it is hollowed, there ants love to stay (this genus are associated with ants). Tips of stems also have stipule, these will exclude, sassafras, poisons ivy, or paper mulberry. (I never see sassafras and poisons ivy in Indonesia, not even in botanical garden, few collector grow paper mulberry. so it is unlikely pop-up as volunteer)

cecropia is not Indonesian natives, but many near botanical garden area, as escapee.. seed are small. chuckerfly are you lives near Bogor, Jakarta or Java island?

lets compare with this

and it will be like this when it get older

to me it is a weed. but if you loves it keep it..could be nice as a pot plant

Ok, I've checked for fragrance, and it smells like.. leaves :D No distinct fragrance.

tofrizal, at the moment I live in Jakarta. The cecropia seedling pictures do look similar. Interesting weed, I'm contemplating to pot it up just for the fun of it.

Update: So, I pulled it out of the Adenium pot a while back.

It started to wilt within a couple of minutes. Planted it in a pot and it wilted some more after a few hours.

The older, bigger leaves became crispy, so I removed those. Finally, I pulled it out of its pot and put it in water. Only 2 top leaves survives and it's growing roots at the moment.

I'll repot after it has a decent amount of new roots. Let's see how it goes..

To be honest it would have been better to leave it in the pot once you'd replanted it and water it well. It would have recovered. Now it will now be disturbed twice. Keep us posted.

I'd leave it in the pot too, but by the end of the first day it wilted and dried so much to the point of collapse. I don't have a picture of this, but it looked dead by this point. So, I put in in water in attempt to try to save it. Only those two leaves recover, the other leaves became crispy and fell off, and the stem firms again after putting it in water.

A little update I want to share with you: the plant survives! It grows more roots while in water and I proceeded to pot it up again. It's now growing a new leaf!
