There are a variety of types of plants in a tropical rainforest. Most species live in tropical rainforests, but they can also be found close to the Arctic Circle. Orchids rely on birds and insects for pollination, much like other flowers. Although temperate orchids usually grow in the soil, tropical orchids are more often epiphytes which grow non-parasitically on trees. Orchids that search for more sunlight through the dense forest canopy actually grow in the top part of tree branches. Every year, it is likely that hundreds of orchid species go extinct as valley systems, especially those along the Andes, are destroyed. Orchids are exceptionally beautiful and range in size from roughly a dime to a CD. With over 20,000 known species, the orchid is one of the most common types of flowers found in tropical rainforests. Orchids can be found throughout the world, and can survive in different kind of habitats. Orchids are known for their striking appearance and their incredible variety. They can mostly be found in Asia and Australia. There can be up to three million seeds in a single orchid seedpod. Orchids are very well-adapted to life in the canopy. Tropical orchids are very beautiful and can be very hard to find. This type of orchid is both an epiphyte (tree dweller) and lithophyte (grows on rocks). Some of these include the banana, orchid, coffee, Brazilian nut tree, and poinsettia. Dendrobiums are also known as “the all- purpose orchids” due to the wide variety of colors and shapes. There are more than 30,000 known species of orchids in the world, and they are capable of growing in many different climates. Nonetheless, there is a huge variety of orchids ranging species that grow on the ground to the 70% of orchids which grow as epiphytes. There are over 20,000 known species and orchids are especially common in moist tropical regions.

The plant life of the Amazon Rainforest is truly phenomenal and among the most spectacular of all the vegetation is the mighty orchid, one of the coolest plants in the jungle. They are brightly colored, which makes th Orchids comprise one of the most abundant and varied of flowering plant families. Seeds like dust. Each type of orchid places the pollinia on a different body part of a different species of bee, so as to enforce proper cross-pollination. The name dendrobium literally means “the one who lives on a tree”. A rare achlorophyllous saprophytic orchid growing entirely underground in Australia, Rhizanthella slateri, is never exposed to light, and depends on ants and other terrestrial insects to pollinate it.
