International Cultivar Registration Authority
(ICRA) for the genus Salix L.
Exploration of the genetic resources of the genus Salix is becoming a specialized science requiring careful
consideration and attention to details when dealing with enormous intraspecific variations and clonal characteristics.
The International Poplar Commission (IPC) of the Food and Agriculture Organization of the United Nations is appointed
as the International Cultivar Registration Authority (ICRA) for the genus Salix by the Special Commission on Cultivar
Registration of the International Society for Horticultural Science (ISHS).
The working party on Taxonomy, Nomenclature and Registration of the IPC acts as the ICRA for willows.
