A vegetatively variable family with herbs and shrubs. Some cultivated members such as some spp. of Berberis and Mahonia have spiny-margined leaves.
What other family that we’ve seen so far this semester had VALVATE anther dehiscence?
Cultivated members: Berberis (barberry), Mahonia (Oregon-grape), Nandina (heavenly-bamboo)
Around here: Podophyllum (may-apple; exceptional characteristics), Caulophyllum (blue cohosh), Jeffersonia (twin-flower)
The Ranunculaceae are extremely variable, yet not too difficult to characterize once you have learned some of the variation in the family. Several members are extremely toxic, including the beautiful Aconitum (Monk’s hood) and Delphinium (larkspur), a popular ornamental. Numerous members of this family are cultivated for their showy inflorescences.
The tricolpate pollen of the Ranunculiids is one of the basic differences that separates this group from the magnoliid dicots and associates it with more derived dicot groups.
