The genus Nuphar consists of yellow-flowered waterlilies and is widely distributed in north-temperate bodies of water. Despite regular taxonomic evaluation of these plants, no explicit phylogenetic hypotheses have been proposed for the genus. We investigated phylogenetic relationships in Nuphar using morphology and sequences of the chloroplast gene matK and of the internal transcribed spacer (ITS) regions of nuclear ribosomal DNA. Two major lineages within Nuphar are consistently resolved with the morphological and molecular data sets. One lineage comprises New World taxa and the other represents a primarily Old World lineage. Relationships within the major lineages were poorly resolved by morphology …

Recent revisionary and cladistic studies in Nuphar Sm. resulted in the following nomenclatural amendments: two novel sections are described (sect. Nuphar and sect. Astylus), five new combinations are proposed (N. advena subsp. orbiculata, N. advena subsp. ozarkana, N. advena subsp. ulvacea, N. pumila subsp. sinensis, N. pumila subsp. oguraensis), and one species, N. oguraensis Miki, is lectotypified.
