Is the resurrection fern a parasite?

No, the resurrection fern (Pleopeltis polypodioides) is not a parasite. It is an epiphytic plant, meaning it grows on other plants, typically trees, but it does not derive nutrients from them. Instead, it absorbs moisture and nutrients from the air and surrounding environment. The fern is known for its remarkable ability to survive extreme dehydration and then quickly revive when water becomes available.
