The Nymphaeales are assigned a key, basal, pivotal evolutionary position in nearly every old and modern system of classification. Over the past three decades many of the studies on this plant group have focused on floral aspects, especially vasculature and developmental studies. In this investigation, literature on the floral vasculature of the taxon has been reviewed with 12 characters selected for cladistic analysis. Results of phylogenetic analysis of floral vascular features are in agreement with other sets of data (e.g. morphological, biochemical, molecular) in retaining the Nelumbonales as a separate order from the Nymphaeales. Floral vasculature features offer less resolution, however, of relationships within the Nymphaeales.
