Overview
The anthophytes were thought to be a clade comprising plants bearing flower-like structures. The group contained the - the extant flowering plants - as well as the Gnetales and the extinct Bennettitales.
Detailed morphological and molecular studies have shown that the group is not actually monophyletic.1] This makes it easier to reconcile molecular clock data that suggests that the angiosperms diverged from the gymnosperms around
Some more recent studies have used the word anthophyte to describe a group which includes the angiosperms and a variety of fossils (glossopterids, Pentoxylon, Bennettitales, and Caytonia), but not the Gnetales.[3]

Taxonomy
The Phylum Anthophyta is further organized into finer groupings including:
- Class (1): Dicotyledoneae
- Species: ZipcodeZoo has pages for 1,924 species, subspecies, varieties, forms, and cultivars in the Phylum Anthophyta.
Classes
Dicotyledoneae
At least 1,132 species and subspecies belong to the Class Dicotyledoneae.
