WHAT DOES SEED FERN MEAN IN ENGLISH?

Pteridospermatophyta

The term Pteridospermatophyta refers to several distinct groups of extinct seed-bearing plants. The oldest fossil evidence of plants of this type is the genus Elkinsia of late Devonian age. They flourished particularly during the Carboniferous and Permian periods. Pteridosperms declined during the Mesozoic Era and had mostly disappeared by the end of the Cretaceous Period, though some pteridosperm-like plants seem to have survived into Eocene times, fossilized in Tasmania. The concept of the pteridosperms goes back to the late 19th century when palaeobotanists came to realise that many Carboniferous fossils resembling fern fronds had anatomical features more reminiscent of the modern-day seed plants, the cycads. In 1899 the German palaeobotanist Henry Potonié coined the term "Cycadofilices" for such fossils, suggesting that they were a group of non-seed plants intermediate between the ferns and cycads.
