Pl. check. 

This is certainly different from Elatostema lineolatum.
I tried to go through the keys in flora of Bhutan, but could not find a match.
Small leaves/ bracts seen opposite normal leaves should be diagnostic

This is Elatostema parvum.
Syn : Elatostema stracheyanum Wedd.

seems to be from family Urticaceae. Grows on moss clade stones along waterbody in moist evergreen forest. Baramura, Tripura 2018 December

Elatostemma sp. 
Yes, Urticaceae...
Looks Elatostema sp.
I am confused between Elatostema papillosum and E. sessile. if I would have collected it would be a lot easier to identify but unfortunately, I didn't. 

Elatostema acuminatum (Poir.) Brongn. ??

This one seems not occur in China so I have no idea.

Thanks, ..., It occurs in China as per Flora of China
