The main plant divisions, in the order in which they probably evolved, are the mosses (Division Bryophyta), the ferns (Division Filicophyta), the horsetails (Division Sphenophyta), the Cycads (Division Cycadophyta), the Ginkgo (Division Ginkgophyta), the conifers (Division Pinophyta), the Gnetophytes (Division Gnetophyta), and the angiosperms (Division Anthophyta).
Angiosperms are the flowering plants that now dominate the plant world (80% of all vascular plants are angiosperms).
Effective 1 January 2005 the Department of Botany was discontinued as an academic unit.
Most former Botany courses will continue to be taught, but under another academic unit (and in some cases under a different course number).
The Teaching and Research Gardens are in the process of being moved to a new location (behind the Earth and Planetary Sciences Building) in connection with renovations to the Hill area.
