Polygonum amphibium L.
A portion of the genus Polygonum was separated as Persicaria leaving only members of the Polygonum aviculare group in the original genus. Whilst generally widely accepted, IPNI and TROPICOS (for example) appear to retain Polygonum as the correct genus for this species, under which name it would be Polygonum amphibium L.
