It is a plant that grows non- parasitically upon another plant and derives its nutrition and moisture from air.
These plants are sometimes called Air Plants because they do not have roots in soil.
Their own genetic material also helps to raise the biodiversity of the forest, but they help increase it in other ways as well. Many provide food and living accommodations for specific insects, birds, bats or other mammals. Without the epiphytes, those creatures would perish, disappearing from the face of the Earth forever.
