Pteridophytes are referred to as botanical snakes as snakes are the first terrestrial animals and so are the Pteridophytes. They are the first true land plants evolving from bryophytes. This is why, sometimes, Pteridophytes are also referred to as ‘snakes of the plant kingdom’ or ‘botanical snakes’.
