Persicaria changhuaensis sp. nov., belonging to P. sect. Echinocaulon (Polygonaceae), from Zhejiang, eastern China, is described and illustrated. The new species is morphologically similar to P. senticosa (Meisn.) H. Gross ex Nakai and P. sagittata (L.) H. Gross ex Nakai var. sieboldii (Meisn.) Nakai, but differs from the former in having an ocrea without a reniform-orbicular wing at apex, pubescent peduncle, triangular bracteoles, white perianth, and stamens exserted from the perianth. Compared to P. sagittata var. sieboldii, it differs in having the leaf blade triangular-hastate, sparsely retrorsely-prickled on abaxial veins, sparsely ciliate at the margin, pubescent peduncle, triangular bracteoles, and stamens exserted from the perianth.
