Abstract:The current classifications of Angiosperms available today, such as those ofHutchinson, Takhtajan, and Cronquist, etc., are by no means phylogeneticbecause they neither reflect the ancestral conditions nor the direction of evolution trends of angiospermous history. The two-dimensional tree-likc diagrams used in the different schemes of classification to represent both the cvolutionary and the classificatory components are untenable. Dahlgren‘s three-dimensional graphic representations of phylogenetic trees in transection in expressing the present-day relationships befween the living plants are more satisfactory. For the full represen-tation of evolutionary relationships, multi-dimensional diagrams would be more desirable.
