Publication: Nat. Arr. Brit. Pl. 2: 270. 1821.

Origin: Native

selected vouchers: WTU

Notes: H&C states introduced from Europe, FNA and JPM state that this species is native.

FNA5: "Persicaria lapathifolia is a morphologically variable complex with more than two-dozen infraspecific taxa described in the New World and Old World. An allozyme study by L. L. Consaul et al. (1991) did not support recognition of elements often referred to Polygonum lapathifolium var. salicifolium or P. scabrum, which are synonymized here. Yang J. and Wang J. W. (1991) reached a similar conclusion regarding var. salicifolium and P. nodosum based on their morphometric analysis."
