Elaeocarpus sveshnikovae, a new name for the fossil-species Elaeocarpus microphyllus (Elaeocarpaceae)
The creation of the International Fossil Plant Names Index (IFPNI 2014 onwards, Doweld 2015) with listing of all fossil plant, algal and fungal species reveals the homonymy between fossil-species belonging to genus Elaeocarpus Linnaeus (1753: 515). The fossil-species Elaeocarpus microphyllus Budantsev & Sveshnikova (1964: 102) was described based on the leaf remains from the Tertiary (Oligocene) sediments near Svetlogorsk, Kaliningrad region, Russian Federation (former East Prussia). However, Elmer (1911) and independently Warburg (1922), proposed the earlier homonyms Elaeocarpus microphyllus Elmer (1911: 1189) and E. microphyllus Warburg (1922: 328) respectively, which were overlooked. According to Art. 53.1 of the ICN (McNeill et al. 2012), a junior fossil homonym, Elaeocarpus microphyllus Budants. & Sveshn. is illegitimate and hence a new name is proposed here. A new nomenclatural act was registered through a pilot registration version in the International Fossil Plant Names Index (IFPNI 2014 onwards), with unique persistent registration barcode (LSID) listed under each newly proposed fossil plant taxon.
