(willow) Introduction The Checklist for Cultivars of Salix L. includes all possible cultivar names with comments. The cultivar name entry may include the following: Epithet. Accepted names are given in bold type. Bibliography. This is presented in parentheses after the epithet whenever available and includes the original botanical name to which the epithet possibly corresponds and also synonyms of the later. Nomenclatural standards (or types) and duplicates (or isotypes) of cultivar names. These are quoted whenever available. Cultivar descriptions based on published references. Descriptions from trade catalogs are included when no other published reference for a name was found. Etymology of the epithet when known. Name status according to the List of Names of Woody Plants: International Standard ENA 2010 – 2015 (Hoffman, 2010) and the Royal Horticultural Society Horticultural Database (2015). Current extent of cultivation and trade according to the Plant Information Online website (http://plantinfo.umn.edu/) for North American nurseries, the RHS Plant Finder website (http://www.rhs.org.uk/plants) for UK nurseries, and the PlantScope website (www.plantscope.nl) for Netherlands nurseries. Awards according to the UK Award of Garden Merit plants and other awards made by the Royal Horticultural Society Council. Notes on the name status according to the International Code of Nomenclature for Cultivated Plants (Brickell et al., 2009) (ICNCP) if the name does not adhere to the ICNCP rules and recommendations. A key to abbreviations of sources is provided as a footnote. The basis for the determination of the name status. For many cultivars of Salix, the requirements for name establishment have not been met due to a lack of accompanying descriptions or references to descriptions in print (as described by the ICNCP). For the purposes of the Checklist, a name is considered “accepted” by the ICRA and listed in bold in this Checklist if any of the following were found: AGM = UK Award of Garden Merit plant and other awards made by the RHS Council CPVO = Community Plant Variety Office database (https://cpvoextranet.cpvo.europa.eu/ ) IPC FAO = International Poplar Commission of the Food and Agriculture Organization of the United Nations LNWP = List of Names of Woody Plants: International Standard ENA (European Nurserystock Association) 2010–2015 or 2005–2010 by M.

(willow) The original published reference of a botanical taxon on which a cultivar name is based or the original published horticultural reference listing the cultivar name with or without a description; A later published reference (such as Rehder [1927, 1940], Spath [1930], Krussmann [1984], etc.) listing the epithet; An electronic reference containing document identifiers (such as USDA NRCS documents); An epithet was filed and registered with the international and national patent offices (CPVO, US PTO etc.), and thus self-established by a grant/patent according to the ICNCP. In addition, to promote uniformity and stability in the nomenclature of Salix, this Checklist has accepted status determinations listed in a few authoritative horticultural databases. Cultivar names listed as preferred names in the List of Names of Woody Plants: International Standard ENA (European Nurserystock Association) 2005-2010 (Hoffman, 2010) and cultivar names listed as accepted names in the Royal Horticultural Society Horticultural Database (RHS, 2015) are considered accepted names in this Checklist even when no published references to these cultivars were found. It is our assumption that these databases base the name status on published sources that we have not be able to locate. The Checklist is a working list of all known Salix cultivar names. It aims to be comprehensive, but not all cultivar information was found. The Checklist will be updated regularly. Corrections of errors or additional information for inclusion in future editions of The Checklist are greatly appreciated. Please send your comments to the author ([email protected]).

(willow) Glossary Accepted name – the earliest name for a cultivar that must be adopted except in specified circumstances (ICNCP Art. 11.1). Cultivar – an assemblage of plants that has been selected for a particular character or combination of characters and that is clearly distinct, uniform, and stable in these characters and that when propagated by appropriate means retains those characters (ICNCP Art. 2.3). ICNCP – International Code of Nomenclature for Cultivated Plants. Isotype (in plant taxonomy) – a plant specimen that is a duplicate of or very similar to the type specimen which can be used as a reference specimen if the type specimen is lost. Standard (nomenclatural) – a specimen or other device to which the name of a cultivar is permanently attached. Standard duplicate – a plant specimen that is a duplicate of or very similar to the nomenclatural standard specimen which can be used as a reference specimen if the standard specimen is lost. Standard portfolio – the arrangement by which a nomenclatural standard and any allied material relating to it are to be kept together. Type (in plant taxonomy) – a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached.
