Taxonomy
The species was first described by André Michaux in 1803.[2] Michaux spelt the epithet "cilinode".[3] Article 60 of the International Code of Nomenclature for algae, fungi, and plants requires the correction of improperly formed "compounding forms",[4] and the International Plant Names Index has corrected it to "ciliinode".[2]
Polygonum ciliinode is part of the tribe Polygoneae of the subfamily Polygonoideae.[5] However, like many species in the family Polygonaceae, it has been placed in different genera within this group, including in Fallopia and Reynoutria.[2] A 2015 molecular phylogenetic study (in which the species was treated as Fallopia cilinodis) found that it was weakly supported as a sister to the "DAP clade" (see the following cladogram), although plastid data alone placed it in the "RMF clade". The presence of extra-floral nectaries in Polygonum ciliinode suggests a relationship with the RMF clade, as this is one of the characteristics of the clade. Its relationships remain unsettled; it may represent an as-yet-unrecognized lineage in the Polygoneae.[5]
