Main Page | See live article | Alphabetical index Spermatophyta, Spermatopsida is the traditional seed-plant division of the kingdom Plantae. A more traditional classification groups all the seed plants together as follows: Spermatophyta Gnetopsida, including Gnetum, Welwitschia, Ephedra Cycadopsida, the cycads Ginkgoopsida, the ginkgo Pinopsida, the conifers, aka Coniferopsida Magnoliopsida, the flowering plants, aka Angiospermopsida A more modern classification splits these groups into individual divisions: Gnetophyta, including Gnetum, Welwitschia, Ephedra Cycadophyta, the cycads Ginkgophyta, the ginkgo Pinophyta, the conifers, aka Coniferophyta Magnoliophyta, the flowering plants Magnoliopsida, the dicots Liliopsida, the monocots There are some botanists who believe that the Magnoliopsida is actually polyphyletic; that is, that it should be split into at least two other classes.
