Other claims from this paper (9)
- Observation Morphological studies of woody Ranales establish the primitive status of the group and its key place in angiosperm phylogeny.
- Observation The carpel of Drimys is ascidial and not conduplicate.
- Observation Morphological data do not support including Degeneria in the Winteraceae.
- Observation Schisandra pollen is interpreted as derived and specialized rather than primitive.
- Observation Berberidaceae, Lardizabalaceae and Menispermaceae share several embryological features.
- Observation Myristicaceae is not closely related to the Annonaceae or the Lauraceae.
- Observation Lauraceae and Calycanthaceae are highly similar in wood, node, flower structure and embryology.
- Observation Ceratophyllaceae is a highly reduced ranalian family derived from a nymphaeaceous stock.
- Observation Numerous primitive features in Paeonia are an argument for retaining it in the Ranales.
