FAMILY INDEX

FAMILY CODE: SCROPH
FAMILY SCIENTIFIC: Scrophulariaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Figwort Family
FAMILY SUMMARY: There is now overwhelming evidence that the Scrophulariaceae as traditionally constituted includes disparate components and requires dismantling (Olmstead & Reeves 1995; Young, Steiner, & dePamphilis 1999; Albach, Meudt, & Oxelman 2005; Schäferhoff et al. 2010, and others). Based on molecular analysis, Young, Steiner, & dePamphilis (1999) suggest that Scrophulariaceae, Antirrhinanthaceae, and Orobanchaceae be restructured to include the current members of Orobanchaceae, Scrophulariaceae, and Callitrichaceae. Beardsley & Olmstead (2002) suggest that Mimulus and Mazus be included with Phryma in a redefined Phrymaceae. Additional changes have been suggested, as summarized below and reviewed and discussed by Schäferhoff et al. (2010).
