PolygalaceaeMartin F. Wojciechowski and Johanna Mahn
Polygalaceae R. Br., a widespread family of ca. 18 genera and perhaps 1050 species, is considered to be monophyletic on the basis of morphological and molecular data (trnL-F; Persson, 2001). This family of trees, lianas and herbs is distributed worldwide except for the western Pacific (e.g., New Zealand). Polygalaceae were traditionally considered to be related to Malpighiaceae or Krameriaceae, all three of which have bilaterally symmetrical flowers that superficially resemble those of Fabaceae, however, analyses of molecular data (rbcL, 18S rDNA and atpB; Soltis et al. 2000; Doyle et al. 2000) place the family as the sister group of Fabaceae.
