A plant that grows on another plant or object above the ground, and which has no roots in the soil. An epiphyte does not parasitize the plant it grows on. but merely uses it for support. It's nutrients are obtained from rainwater, organic debris such as leaf litter, or from the air. The greatest diversity of epiphytes is found in tropical areas and includes many orchids.
