Sagittaria trifolia L. ??
Yes it’s Resembles …
Not Sagittaria trifolia at all as per images herein.
I think it is Alisma lanceolatum With. as per images and details herein.
I don’t think this is Alisma lanceolatum because the the leaves are not lanceolate, but sagittate (although flowers look very similar). But, I also doubt that this is Sagittaria trifolia either because, even though the leaf is sagittate, it’s not sharply arrow-like as is typical of S. trifolia (as the name Chinese Arrow-head suggests). So, I have a feeling that this could be an different species altogether.
