The Orchid family consists of 735 genera and more than 17,000 species. Orchids can be found in most parts of the world. The tropics, however, has the most diversity. Most tropical orchids are epiphytes.
Unlike most of the plants which are terrestrial, epiphytic orchids cling themselves literally high and dry on tree branches. To adapt to the harsh living conditions, epiphytic orchids have evolved over millions of years in many ways to conserve water. Their roots are covered with velamen to absorb moisture from the air, while their stems have converted to pseudobulbs to store water. The leaves of epiphytic orchids perform Crassulacean Acid Metabolism (CAM) type of photosynthesis so that they do not have to take in CO2 during the day and by not doing so, they prevent the loss of water via the opened stomata in the hot day. They can even absorb nutrients through their leaves. With all these adaptations, epiphytic orchid plants needs to be grown differently from other terrestrial plants.
