This is very definitely a sp. of Ludwigia, family Onagraceae, looks like Ludwigia perennis.

It is Ludwigia perennis. Sorry I mixed up the name and author of reference book. Identification help was obtained from "Aquatic and Wetland Plants of India" by C.D.K.Cook published by Oxford University Press in 1996.

Dear Susmita,

 

You identified it as Ludwigia perennis.

 

But kindly see the link for Ludwigia perennis.

http://www.aquaticcommunity.com/tr/Ludwigiaglandulosa.php

 

In the link the colour of the leaves are purple but in my case the leaves are always green. Not only that when I went for image search for Ludwigia perennis

all the pictures shows same purple colour of leaves.

 

Another point, I learnt from the above site that Ludwigia perennis is a water plant. But I always found them far away from any water body.

 

Again, I found a match with my posted pictures with Ludwigia octovalvis.

 

See the link for Ludwigia octovalvis.

Waiting for your comments.

 

With regards,
