In Ranunculales, one of the most advanced orders of the subclass Magnoliidae, the general evolutionary trend from woody to herbaceous plants appears to have been reversed.
Evergreen and deciduous trees and shrubs are found in the Magnoliidae, as are perennial herbs...
The reproduction and life cycles of the more primitive extant members of the Magnoliidae reflect stages in the life histories of the early angiosperms that cannot be found in the fossil record.

 PBIO 450 Lecture Notes - Magnoliidae -- Spring 1999
When Cronquist (1981) reviewed the order Papaverales he indicated that he was uncertain if the name had been validly published and provided a full and direct reference to a validating description in Latin.
Unknown to him, and to the systematic community in general, was that the Belgian politician and botanist Count Barthélemy Charles Joseph Dumortier (1797-1878) proposed numerous ordinal names in his book Analyse des familles des plantes published in 1829.
The definition of Papaverales given by Cronquist (1981, 1988) as two families with some 600 species is that traditionally used.

 PBIO 450 Lecture Notes - Magnoliidae -- Spring 1999
While both Takhtajan (1997) and Reveal (1997) adopted several additional orders and divide up a few of the families, the membership of the complex is not particularly different: Lardizabalaceae, Sargentodoxaceae, Menispermaceae, Nandinaceae, Berberidaceae, Ranzaniaceae, Podophyllaceae, Ranunculaceae, Kingdoniaceae, Circaeasteraceae, Hydrastidaceae, Papaveraceae, Pteridophyllaceae, Hypecoaceae and Fumariaceae (fide Takhtajan).
All of these families form a distinct core with Cronquist defining the Ranunculales and Papaverales as those basically terrestrial members of the Magnoliidae without ethereal oil cells and with triaperaturate pollen.
His distinction between Ranunculales and Papaverales was based on the number of sepals (more than two in the former, only 2 in the latter) and the generally apocarpous (Ranunculales) versus syncarpous (Papaverales) pistil.

 Order Papaverales   (Site not responding. Last check: 2007-10-17)
The Poppy Order (Papaverales) is grouped with the fairly primitive Angiosperms and is probably the most highly-evolved order in this group.
It is likely that Papaverales evolved from the ancestors of the Buttercups (Ranunculales).
Some plants in this order produce a chemical, a kind of alkaloid, that discourages animals from eating them.
