Nomenclatural standards of five iris cultivars, namely ‘Andrey Kniazev’, ‘Eduard Regel’, ‘Marishka’, ‘Temuri’, and ‘Vitosha’ bred at the Peter the Great Botanical Garden of the V.L. Komarov Botanical Institute of RAS have been prepared in accordance with the rules and recommendations outlined in the International Code of Nomenclature for Cultivated Plants, and in the VIR methodological guidelines for the vegetatively propagated plants. Each nomenclatural standard is one herbarium sheet with all parts of a flowering plant accompanied by photos of flowers. Nomenclatural standards are registered in the VIR Herbarium database and deposited in the Herbarium of Cultivated Plants of the World, their Wild Relatives and Weeds (WIR) at the National Center for Plant Genetic Resources.
