Hi! Can you help me determine the scientific name of this plant? It is for our thesis. Thank you very much!
That could also be Phyllanthus. I can't tell from your photos - does it have tiny flowers below its leaves?
Phyllanthus amarus and P. urinaria are common herbaceous species in SE Asia, both with this general appearance. You would need to see fine detail to identify the species vwith certainty.
