Common names include lady's thumb, spotted lady's thumb, Jesusplant, and redshank.〔(''Persicaria maculosa''. ) Germplasm Resources Information Network (GRIN).〕 It is widespread across Eurasia from Iceland south to Portugal and east to Japan.〔(Altervista Flora Italiana, ''Persicaria maculosa'' Gray ) includes photos and European distribution map〕〔(Flora of China, ''Polygonum persicaria'' Linnaeus, 1753. 蓼 liao )〕 It is also present as an introduced and invasive species in North America, where it was first noted in the Great Lakes region in 1843 and has now spread through most of the continent.〔(【引用サイトリンク】url= http://www.glu.org/en/node/199 )〕〔(Biota of North America Program 2014 state-level distribution map )〕 The oldest name available for this species is ''Polygonum persicaria'', coined by Linnaeus in 1753. In transferring the species from ''Polygonum'' to ''Persicaria'', the name ''Persicaria persicaria'' cannot be used because using the same word for both parts of the scientific name is prohibited by international argeement.〔(International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) ) see section 23.4〕 ==Description== ''Persicaria maculosa'' is an annual herb up to tall, with an erect rather floppy stem with swollen joints. The leaves are alternate and almost stalkless. The leaf blades often have a brown or black spot in the centre and are narrowly ovate and have entire margins. Each leaf base has stipules which are fused into a stem-enclosing sheath that is loose and fringed with long hairs at the upper end. The inflorescence is a dense spike. The perianth of each tiny pink flower consists of four or five lobes, fused near the base. There are six stamens, two fused carpels and two styles. The fruit is a shiny black, three-edged achene. This plant flowers from July to September in the temperate Northern Hemisphere.〔〔(【引用サイトリンク】title=Redshank: ''Persicaria maculosa'' )〕〔(Flora of North America, ''Persicaria maculosa'' Gray, 1821.
