IFPNI registration lsid:— A3325DB9-C6AD-4090-8C0A-63843BE792C0

Note:— Dorofeev (1963: 167) in describing the new fossil fruit from Western Siberian sediments of the Oligocene as a distinct species Polygonum reticulatum , failed to indicate the holotype, making the name as not validly published (Art. 40.1) (see IFPNI: http://fossilplants.info/names/ 8CE3CE9F-C952-44D8-A4A4-B6A9FADA6144). Arbuzova (2006: 24) later validated the species (see IFPNI: http://fossilplants.info/names/ 145745A3-77A8-42DF-BD89- D0511F61E3E8), but overlooked that P. reticulatum is a later homonym of two previously and validly published extant names by Koch (1849: 200) and de Bruyn (in Miquel 1854: 309) (the Koch’s name has nomenclatural priority). A replacement name for fossil P. reticulatum is therefore here proposed.
