Abstract
Comparative investigations of serological characters of seed proteins from taxa regarded as members of theSaxifragales result in the recognition of two distinct groups of related families. One consists of theSaxifragaceae, Grossulariaceae, andCrassulaceae; to itHamamelis, and possiblyPenthorum and theRosaceae may be connected. The second group contains theHydrangeaceae, Escalloniaceae, Roridulaceae, Cornaceae, andCaprifoliaceae; it is rich in iridoid compounds, has more derived morphological characters, and seems to represent a monophyletic line block. ThePittosporaceae were not found to be linked with either of the two groups, but rather show similarities with members of theApiales. All these data support systematic arrangements proposed byDahlgren (1975a).
