Etymology: "Pteridophyte" is built from two Greek elements: "pteris" (genitive "pteridos"), meaning "fern," and "phyton," meaning "plant." The combining form "pterido-" comes from the Greek stem of the first word, while "-phyte" is the familiar suffix found in words like "epiphyte" and "hydrophyte," where it marks a plant of a particular kind or habit. The word is a modern scientific coinage, not an ancient one. Ancient Greeks had no single term for this group of plants, so botanists assembled one from classical parts when they needed a name for ferns, horsetails, clubmosses and their relatives. Its meaning is precise: a vascular plant that reproduces by spores rather than seeds, which distinguishes it from flowering plants and conifers. The ferns in the name are its best-known members, and the term groups them with the other spore-bearing vascular plants under one heading.
