¿ Eichhornia ?
Dear friends,
The flower looks like a miniature version of any Eichhornia; or may be I am mistaking. I could not make out any leaf of this plant among the mix of many others. Please help with the ID of this aquatic plant.

Pontederia sp. [Pontederiaceae]. Most probably P. cordata L.

Thank you very much … for the ID; I am finding Pontederia cordata L. convincing. Thank you very much.
