Eventhough the pteridophytes living in land and depends on water for sexual production the. Why we are not calling it also a amphibians of plant kingdom

[@kim54688]

I guess because they are vascular with definite xylem and phloem so they are not the true amphibians of the plant kingdom rather they are known as vascular amphibians.
