The Polygonaceae are a familyofflowering plants known informally as the knotweed familyorsmartweed—buckwheat family in the United States. The nameisbased on the genusPolygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum.[2] The name may refer to the many swollen nodes the stems of some species have, being derived from Greek [poly meaning 'many' and gony meaning 'knee' or 'joint']. Alternatively, it may have a different origin, meaning 'many seeds'.[3]
Polygonaceae are very well-defined and have long been universally recognized. In the APG III system, the family is placed in the orderCaryophyllales.[1] Within the order, it lies outside of the large clade known as the core Caryophyllales.[11] It is a sister to the family Plumbaginaceae, which it does not resemble morphologically.[12]
Brandbyge wrote descriptions for 43 genera of Polygonaceae in 1993.[7] Since then, a few more genera have been erected, and some segregatesofBrunnichia, Eriogonum, and Persicaria have been given generic status in major works.[6][14][16] Some of the genera were found not to be monophyletic and their limits have been revised. These include Ruprechtia, Eriogonum, Chorizanthe, Persicaria, Aconogonon, Polygonum, Fallopia, and Muehlenbeckia.
