Eocene

The Eocene is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma).

Evolutionary history of plants

The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved through endosymbiosis, through multicellular marine and freshwater green algae, to spore-bearing terrestrial bryophytes, lycopods and ferns, and eventually to the complex seed-bearing gymnosperms and angiosperms (flowering plants) of today.

Flowering plant

Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae, commonly called angiosperms.

Ginkgoales

Ginkgoales are a gymnosperm order containing only one extant species: Ginkgo biloba, the ginkgo tree.

Glossopteridales

Glossopteridales is an extinct order of seed plants, known from the Permian of Gondwana. Corystospermaceae and Glossopteridales are Permian plants, Pteridospermatophyta and Triassic plants.

Gondwana

Gondwana was a large landmass, sometimes referred to as a supercontinent.

Gymnosperm

The gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes, forming the clade Gymnospermae.

International Code of Nomenclature for algae, fungi, and plants

The International Code of Nomenclature for algae, fungi, and plants (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".

Ovule

In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells.

Pteruchus is a form genus for pollen organs of the seed fern (Pteridospermatophyta family Umkomasiaceae. It was first described by Hamshaw Thomas from the Umkomaas locality of South Africa. It is associated with the seed bearing organs Umkomasia and Dicroidium leaves. Corystospermaceae and Pteruchus are Pteridospermatophyta and Triassic plants.
