Archaeopteris is a member of a group of free-sporing woody plants called the progymnosperms that are interpreted as distant ancestors of the gymnosperms. Archaeopteris reproduced by releasing spores rather than by producing seeds, but some of the species, such as Archaeopteris halliana were heterosporous, producing two types of spores.

Theophrastus's Enquiry into Plants or Historia Plantarum (Ancient Greek: Περὶ φυτῶν ἱστορία, Peri phyton historia) was, along with his mentor Aristotle's History of Animals, Pliny the Elder's Natural History and Dioscorides's De materia medica, one of the most important books of natural history written in ancient times, and like them it was influential in the Renaissance.
Wattieza was a genus of prehistoric trees that existed in the mid-Devonian that belong to the cladoxylopsids, close relatives of the modern ferns and horsetails. The 2005 discovery (publicly revealed in 2007) in Schoharie County , New York , of fossils from the Middle Devonian about 385 million years ago united the crown of Wattieza to a root ...
