Orchidaceae or the orchid family is a worldwide family of about 880 genera and more than 20,000 perennial epiphytic or terrestrial species in order Asparagales. Each flower has 3 sepals and 3 petals borne above a 3-chambered ovary. Many grow from a tuber or a rhizome and have an intricate structure that has evolved from their pollination strategy. Seeds are short-lived, often tiny and fine and may need to form an internal root association with a soil fungus in order to give rise to new plants.
