Taxonomy Narcissus tip necrosis virus was isolated in 1972. At the 1987 ICTV meeting, that proposed the genus Carmovirus, Narcissus tip necrosis virus was listed as a 'tentative' memberMINUTES OF THE 7th MEETING OF THE ICTV EDMONTON, CANADA, 12th AUGUST 1987 but as of the 2013 releaseICTV Taxonomy History for Carmovirus it had not been officially accepted. Note that the ICTV does not track tentative members,ICTV Taxonomy Release History so there are no further records in their databases, though NTNV was still listed as tentative in the Ninth Report (2009).
