The term used in botany and horticulture. Epiphyte is a Greek word ‘epi’ meaning ‘upon’ and ‘phyton’ meaning plant. Epiphytes are the plants which grow upon another plant. In true sense the epiphytes are not parasites. They only takes the support of the other plants (small to big bushes and trees) for their survival throughout entire life cycle but does not part with the nutrients of the host plant. They absorb moisture and nutrients from air, rain and dead bark of their host. Few epiphytes produce spongy aeriel roots to absorbed moisture and nutrition from atmosphere (ferns and its allies).
