Comparative Chemistry and the Relationship of the Hamamelidaceae

Abstract

IN many of the more recent systems of classification, the Hamamelidaceae have been given a central position, several authors believing that they have been derived from rosalian or magnolialian ancestors, and that they, in turn, have given rise to some of the amentiferous families. Although the family is usually included in the Rosales, a number of systematists have assigned it to the order Hamamelidales.
