spongy roots observed found floating just beneath the water surface, where rock is the substrate


Could this be Ludwigia octovalvis (Jacq.) Raven of Onagraceae? Flowers 2 – 3cm across.


… the flower size seems to be on larger side for L. octovalvis … have seen them to be about 7 – 12 mm …. not sure about variable size.
Let us wait for comment(s).


Petals could be up to 17 mm long and up to 17 mm broad according to Flora of China.


Ludwigia octovalvis indeed commonly knon as ” Ban Lavanga” from Onagraceae profusely found in Pachmari region of M.P. A similar Plant is found in waste land of Bengal, It is has a smaller size flower rest looks very similar known as Jussiaea suffruticosa L. 


Thank you … for clarity on flower size … thus, it does seem to me L. octovalvis


This does not look like Ludwigia octovalvis [L.parviflora]. Will send photographs of L. octovalvis for comparison later if required.


It is Ludwigia peruviana (L.) H. Hara, (syn: Jussiaea peruviana L., Sp. Pl. 388. 1753. = Jussiaea speciosa Ridley, J. Bot. 59. 1921)

It is a weed, originally came from America


For me also this looks more like Ludwigia peruviana (L.) Hara of Onagraceae owing to the presence of Hirsute plant body.

…, could you please upload pictures of L. octovalvis for comparison purpose?


As requested.

Perhaps a Ludwigia sp. (may be Ludwigia canescence?) please ignore any mistakes in specific epithet.


This aquatic plant is Ludwigia peruviana (L.) Hara of Onagraceae.

These two plants are snapped from Wayanad district, Kerala. Please help in identification.


Can IMG_0081.jpg be an Onagraceae member like Ludwigia species? 


IMG_0081.jpg — looks like Ludwigia, and most probably L. hyssopifolia 


Thanks, …
Here are links of Ludwigia hyssopifolia:

Appears to be Ludwigia peruviana (L.) H.Hara as per images herein and as per keys at Ludwigia   


Perhaps DSCF8028.jpg is Crinum ¿ asiaticum ?

and IMG_0081.jpg could be Ludwigia peruviana just as Garg ji has suggested.


Yes, I was talking about 2nd image.
