This seems to be the Jussiaea repens L. of the Bengal Plants i. 507., KESARA-DAM (কেশর-দাম) in Bengali, an aquatic floating herb with erect offshoots.

Cattle grazing area, soil is generally wet all the time

‘Ludwigia adscendens?’
Likely.
Good quality images.
Can you give some details like:
– was the plant prostrate? well branched?
– stamen count 10 or 8? (stamens on the far side are hidden from view)
-adventitious roots present or not

1) Plant was prostrate and well branched yes. Only the flowering portions ‘stuck out’ making the the plant noticeable amongst the grass.
2) Stamen number seems to be 8 and 9 in the flowers I have photographed. I have attached photos showing clear view of all stamens.
3) this I did not notice about the plant. I will be visiting the same area in a week or so, I will note it then and get back to you.

Though flowers should be (creamy) white with yellow at the base of petals (as per my record, and description in old lit. and FoC), yet I agree, seeing available images of yellow flower in the net.

Thank you … for the response. My experience is Ludwigia adscendens may not be always found as long trailing/ prostrate herb, erect parts sometimes get detached and found as small erect herb, specially when water level recedes.

Yes sir. I had been to the same area today but could not find the plant. Otherwise I would have made sure to check for adventitious roots. And I agree, the plant I found fits your latter description based on what I saw 2 weeks back.

Guess Jussiaea repens

Sir ji I think you are correct of this plant being Jussiaea repens

I thought of Ludwigia!!

But Jussiaea repens leaves look linear and bit different to this one.

Appears to be Ludwigia adscendens
