The 'Takhtajan System' of flowering plant classification (Armen Takhtajan. 1997. Diversity and Classification of Flowering Plants) treats flowering plants as as a division or phylum (Magnoliophyta) with two classes (monocots and dicots) which are organized into Subclasses. Higher level organization is similar to the Cronquist System, but a bit more complex. However, Takhtajan uses the Superorder as the basic unit of the Subclass and this pattern of organization is also used in the Thorne System of flowering plant classification.
