Abstract
A new species of Nuphar (Nymphaeaceae), N. submersa, from Tochigi Pref., central Japan is described. This new species is characterized by its thoroughly submerged habit and narrowly oblong-triangular submerged leaves without the sinus. This species is also different from both N. japonica and N. oguraensis in the color of anthers and fruits. A phylogenetic study based on the AFLP fragments showed that both N. submersa and N. oguraensis were sister taxa but well separated phylogenetically.
