Word origin

The term 'pteridophyte' is derived from the Greek words 'pteron', meaning 'wing' or 'feather', and 'phyton', meaning 'plant'. The term reflects the often feathery appearance of many ferns, which are the most recognized members of this group. Pteridophytes have existed on Earth for over 360 million years, populating a wide variety of habitats, primarily moist environments. They represent crucial stages in the evolution of land plants, transitioning from simple, non-vascular forms to more complex vascular plants. Throughout history, pteridophytes have contributed significantly to the planet's biodiversity and ecology, providing habitat and food for various organisms.
