FAMILY INDEX

FAMILY CODE: BERBER
FAMILY SCIENTIFIC: Berberidaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Barberry Family
FAMILY SUMMARY: As broadly defined here, a family of about 15 genera and 650 species, herbs and shrubs, of the temperate Northern Hemisphere and Andean South America. There has been much debate and study of whether the Berberidaceae should be recognized as a broadly defined unit, or split into a variety of segregate families (such as Podophyllaceae, Epimediaceae, Nandinaceae, Leonticaceae). Based on molecular studies, Kim & Jansen (1996, 1998) and Kim et al. (2004) conclude that division of the Berberidaceae into segregate families is not warranted.
