Gymnosperms are a division of plants, not a single species. There is no single scientific name for all gymnosperms.

However, the division of gymnosperms is called Pinophyta, which encompasses all the different types of gymnosperms.

Here are some examples of gymnosperm groups:

* Coniferophyta: Conifers like pines, firs, and spruces

* Cycadophyta: Cycads

* Ginkgophyta: The ginkgo tree

* Gnetophyta: Gnetum, Ephedra, and Welwitschia
