The other possibilities are Alisma lanceolata, which has lance shaped leaves, and Damasonium minus, the fruits of which are triangular.

Thanks again Jane.
Sagittaria platyphylla seems more likely. As for the other sighting I had my doubts about the ID of Alisma plantago-aquatica at the time, but didn't know an alternative.

Thanks for the quick confirmation Michael M. Will keep a lookout for this one.
