Data from: Nomenclatural revision of <em>Pinguicula</em> (Lentibulariaceae) in the Baltic and Nordic countries including their oversea territories and Iceland

Names in the genus Pinguicula established for taxa from the Baltic and Nordic countries, including their overseas territories and Iceland, were analyzed to provide nomenclatural and taxonomic clarity. Of the 33 names retrieved from the literature and online databases, one is illegitimate, two are invalid, and 16 were found to require typification. Nine lectotypes and three neotypes were designated, while four names remain untypified due to the absence of suitable material.
