GYMNOSPERMAE
Gymnosperms
“Gymnosperm” comes from the composite Greek for “naked seed” or “revealed seed,” in contrast to the ovule-enclosed angiosperms. These seeds form in scales on leaves, in cones, or singularly (in the case of yew).
This grouping of plants includes all coniferous trees, as well as a few other relevant tree and shrub groups. These divisions are of great note, and include the following genera:
- Pinophyta (Conifers)
- Pinales
- Cupressaceae
- Cupressus (Cypress)
- Juniperus (Juniper)
- Pinaceae
- Abies (Fir)
- Cedrus (Cedar)
- Cryptomeria (Japanese Cedar)
- Larix (Larch)
- Picea (Spruce)
- Pinus (Pine)
- Taxaceae
- Taxus (Yew)
- Ginkgoopsida
- Ginkgoales
- Ginkgoaceae
- Ginkgo
- Gnetophyta
- Ephredales
- Ephedraceae
- Ephedra

DIVISION: Pinophyta/Coniferophyta
Class: Pinopsida
Order: Pinales
Conifers are the cone-bearing seed plants within the Gymnosperm clade. They form the division Pinophyta (also called Coniferophyta), and the class Pinopsida.
While there have been a number of propositions for distinguishing this order into multiple subclasses, relevant to our research we will be treating the following families as belonging to this order:
- Pinophyta (Conifers)
- Pinales
- Cupressaceae
- Cupressus (Cypress)
- Juniperus (Juniper)
- Pinaceae
- Abies (Fir)
- Cedrus (Cedar)
- Cryptomeria (Japanese Cedar)
- Larix (Larch)
- Picea (Spruce)
- Pinus (Pine)
- Taxaceae
- Taxus (Yew)

DIVISION: Ginkgophyta
An ancient division of gymnosperms with only 1 surviving genus, Ginkgo, and 1 species, Ginkgo biloba.
- Ginkgoopsida
- Ginkgoales
- Ginkgoaceae
- Ginkgo
* * * * * * *
DIVISION: Gnetophyta
This is a division containing only 3 genera, the only 1 of which is relevant to our interests (as far as we are aware) is Genus Ephedra.
- Gnetophyta
- Ephredales
- Ephedraceae
- Ephedra
