subdivision = See textRanunculales is an order of
flowering plant s. Of necessity it contains the familyRanunculaceae , thebuttercup family.The
APG system (1998) and theAPG II system (2003) both recognize the order and place it among the basaleudicots , not assigned to a further clade. These systems use this circumscription:
* order Ranunculales
*: familyBerberidaceae
*: familyCircaeasteraceae
*:: [+ familyKingdoniaceae ]
*: familyEupteleaceae
*: familyLardizabalaceae
*: familyMenispermaceae
*: familyPapaveraceae
*:: [+ familyFumariaceae ]
*:: [+ familyPteridophyllaceae ]
*: familyRanunculaceae Note: "+ ..." = optional segregrate family, that may be split off from the preceding family.Under this definition, well-known members of Ranunculales include
buttercup s,clematis , columbines,delphinium s, and poppies.The
Cronquist system (1981) also recognised the order, but placed it in the subclassMagnoliidae , in classMagnoliopsida [= dicotyledons] . It used this circumscription:
* order Ranunculales
*: familyRanunculaceae
*: familyCircaeasteraceae
*: familyBerberidaceae
*: familySargentodoxaceae
*: familyLardizabalaceae
*: familyMenispermaceae
*: familyCoriariaceae
*: familySabiaceae In the Cronquist system the Papaveraceae and Fumariaceae (including the plants in the optional family Pteridophyllaceae) were treated as a separate order
Papaverales , placed in this same subclass Magnoliidae.External links
