pteridospermatophyta

The genus is placed in the division Pteridospermatophyta.

Plants from the division Pteridospermatophyta notably Adiantites have been identified.

Glossopteridales is an extinct order of plants belonging to Pteridospermatophyta, or Seed Ferns.

The major divisions of flora that have been recognized include: Lycopodiophyta, Arthrophyta, Pteridophyta, and Pteridospermatophyta.

The most plausible ancestral group for the order Ginkgoales is the Pteridospermatophyta, also known as the "seed ferns", specifically the order Peltaspermales.

Beginning in the Late Mississippian, forests of Lycopodiophyta, Arthrophyta, Pteridophyta, and Pteridospermatophyta began to grow in these plains.

Widespread coal swamp deposits across North America and Europe during the Carboniferous Period contain a wealth of fossils containing Lepidodendron up to 30 meters tall, abundant Gymnosperm, such as conifers and Pteridospermatophyta, and countless smaller, herbaceous plants.
