It is interesting
Whether it is Ludwigia octovalvis or Ludwigia perennis? Only significant difference between the two what I noticed from the literature is that the small petiole is winged in L.perennis.
Mohina ji Can you check this in your plant as it is not appreciated in the given picture.
Otherwise the plant looks close to Ludwigia octovalvis to me

Dear Satish ji,

As per the key provided in this link (http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=119063) and the description and illustrations therein shows that the stem leaf margin of L. octovalvis is hairy and the same for L. perennis is glabrous. 
In this pictures, though it is not very clear, seems that the plant is glabrous.  
Mohima ji please check whether the plant is hairy or not. 



Regards,
Giby
