Nomenclatural novelties in Nuphar (Nymphaeaceae)
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.
