Serological Aspects and Phylogenetic Relationships of the Magnoliidae

Summary Serological comparison of the major seed proteins from angiosperms, i.e. the legumin‐like proteins, indicate close phylogenetic connections between Magnoliidae, Hamamelididae and Corniflorae (sensu Dahlgren, 1980) and refute the idea of their independent evolution. These proteins also confirm the homogeneity of the iridoid producing Corniflorae, and advocate the inclusion of the Gentianaceae within the Corniflorae.
