Orchid

There are 22,000 accepted species of Orchidaceae in the world - some experts believe there could be between 25,000 and 30,000 (or more) in total. Around 800 new species are described each year! This huge radiation is at least partly due to the coevolution between orchids and their species-specific pollinators.
