This research proposal will focus on present hypotheses on the evolution of morphological characters. In recent years, molecular techniques generated a tremendous amount of data which can be interpreted unambiguously, namely the nucleotide positions of the genome. However, recent classification hypotheses are often based on molecular data only and consequently they are not always supported by morphological evidences. New Evolutionary Morphology (NEM) tries to reassess morphological characters using molecular insights. The reconsideration of characters will clarify the underlying patterns of character evolution. Therefore, NEM contributes to a better understanding of evolutionary relationships among flowering plants.
