I believe Ehrendorfer uses Rosopsida as a formal taxon name for eudicots.--Curtis Clark 04:48, 10 January 2007 (UTC)
- That may be so, in which case the information should be included. I haven't seen the reference so I've left it out. But be careful--at least in the sense of Reveal, "Rosopsida" is not precisely equivalent to the eudicots. In both cases I assume it's an attempt to recognize that the dicots are a paraphyletic taxon, and that the name Magnoliopsida (which is equivalent to the dicots in the Cronquist system) is attached to a group of angiosperms that diverged before the split between the monocots and the eudicots.

- de:Rosopsida redirects to de:Dreifurchenpollen-Zweikeimblättrige, which states (translation by Bablefish, fixed by me):
In der Systematik der Biologie ist diese Gruppe erst vor wenigen Jahren neu festgelegt worden, als man mit moderner Technik den neuen Typus von Pollenkorn erkannte. In manchen Systemen wird sie als dritte Klasse neben die Einkeimblättrigen und restlichen Zweikeimblättrigen gestellt. Oft wird sie auch als Eudicots oder Echte Dikotyledonen bezeichnet. Man nimmt an, dass sich das Dreifurchen-Pollenkorn etwa vor 65 Mio. Jahren (Wende Kreide- Tertiärzeit) herausgebildet hat. (In systematic biology this group was first recognized only a few years ago, when the new type of pollen grain was recognized with modern technology. In some systems it is placed as the third class beside the monocots and remaining dicots. Often it is also called "Eudicots" or "genuine dicots". One assumes that the three-furrow polling grain developed approximately 65 million years ago (around the K-T boundary).
- The article includes a list of taxa, but unfortunately no references.
- fi:Rosopsida cites the Angiosperm Phylogeny web site, which of course doesn't mention it. it:Rosopsida redirects to it:Eudicotiledoni. de:Systematik der Bedecktsamer cites E. Strasburger, P. Sitte, H. Ziegler, F. Ehrendorfer, A. Bresinsky: Lehrbuch der Botanik für Hochschulen. Begründet von E. Strasburger ... Gustav Fischer, Stuttgart 1998 (34. Aufl.), Spektrum Ak. Verl., Heidelberg 2002 (35. Aufl.). ISBN 3-8274-1010-X, which I believe is the reference for equating the eudicots with the Rosopsida.--Curtis Clark 06:08, 10 January 2007 (UTC)
