Ranunculidae. Eudikotyledonen. Merkmale[Bearbeiten] Die Eudikotyledonen besitzen wie die basalen Ordnungen der Bedecktsamer zwei Keimblätter.
Bei ihnen fehlen allerdings deren ätherische Öle in Idioblasten. Die Organe der Blüte stehen in Wirteln. Die Pollenkörner besitzen drei Keimfurchen (sind tricolpat) oder sind davon abgeleitete Formen. [1] Stem eudicotyledons. Eudicotyledons. Eudicots. Relationships after Savolainen et al. 2000b and Hilu et al. (2003).

Eudicots. Arabis pollen has three colpi.
The Eudicots, Eudicotidae or Eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots.[1] The close relationships among flowering plants with tricolpate pollen grains was initially seen in morphological studies of shared derived characters.
