Think it belongs to same species, but shoot at different place.
 
Would you please identify this plant.

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.
 
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,
 
Debasish Joardar
