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.
