Floristics & Taxonomy Schori, Melanie [1]. Updating Citrus Nomenclature and Classification. Recent phylogenetic and genomic studies have substantially changed current understanding of relationships among cultivated Citrus. Several species are now recognized as the ancestral parents of economically important hybrid taxa including oranges, grapefruit, lemons, limes, and mandarins. Although whole-genome sequencing is verifying the parentage of an increasing number of cultivars, Citrus nomenclature and classification have not kept pace. Two competing classifications from the 1960s, Tanaka and Swingle & Reece, are still widely used and include many names that should be synonymized. An ad hoc committee was formed in 2017 to explore classification options and make recommendations for nomenclatural changes that will best serve the scientific and horticultural communities. Items under consideration include the circumscription of Citrus, the treatment of nothotaxa, and the use of cultivar and Group names to reflect morphological differences while complying with provisions of the International Code of Nomenclature for Algae, Fungi, and Plants and the International Code of Nomenclature for Cultivated Plants. Updates on the committee's progress are presented.
