| Research Abstract |
The results of presumption on the extant dicotyledons that are most closely related to the monocotyledons were not constant depending on the materials and methods used for the study. It was a group of Magnoliales and Laurales when we used a method of maximum parsimony with a material of Ceratophyllales. It was Piperales when we used maximum parsimony without Ceratophyllales. And, it was a group of Piperales, Magnoliales and Laurales when we used a method of maximum likelihood regardless of Ceratophyllales. However, the bootstrap values were low in all cases. Recently, it was often reported that it was a group of eudicots and Ceratophyllales. However, the present results did not support the relationship.
