Another unknown 0029: Water-pepper, perhaps?

Could be Knotgrass - Polyganum aviculare.

I considered that, but the flower heads didn't seem right, and I had
an impression -- perhaps wrong -- of greater size. But your shot is
at least as good as mine.

Question: does water-pepper taste good enough to be used in food?
