Stabilised Plant Names
The current ISTA List of Stabilised Plant Names represents the 7th edition of this work. Previous editions were completed and published in 1966, 1983, 1988, 2001, 2007, and 2013. Individual names on the List are to be stabilised for a period of at least six years. After a 13-year hiatus following the 1988 edition, numerous changes were made for the 2001 edition, so the ISTA Nomenclature Committee thereafter refrained from proposing changes to any name, regardless of its initial date of stabilisation, until the 2007 edition. With this 2019 edition, we are continuing the regular cycle of publication established for the last three editions.
Although only six years have elapsed, many changes or adjustments in nomenclature for the plants treated here have occurred. These mostly result from recent advancements in taxonomic classification or from the nomenclatural actions of an International Botanical Congress, the latter reflected in the 2018 International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code) (ICN) adopted by the 2017 Shenzhen Congress (N. J. Turland et al., Regnum Vegetabile 159, Koeltz Botanical Books, 2018). Proposed changes to the List were evaluated individually by Nomenclature Committee members and voted upon. From these results, a document containing the "Proposed Changes to the ISTA List of Stabilised Plant Names" approved by Committee vote was submitted to and approved by the 32nd ISTA Congress in Hyderabad, India, in 2019. At the Congress, ISTA members recommended that codes used by the International Union for the Protection of New Varieties of Plants (UPOV) be added to the List. The current list includes UPOV codes and links to their GENIE database.
