The Telegraph Plant (Codariocalyx motorius, often placed in Desmodium[1]), also known as Semaphore Plant, is a tropical Asian shrub, one of a few plants capable of rapid movement; others include Mimosa and the Venus Flytrap.
It is widely distributed throughout Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, Taiwan, Thailand and Vietnam. It can even be found on the Society Islands, a remote chain of islands in the South Pacific. It produces small purple flowers. Telegraph Plant contains small amounts of tryptamine alkaloids in leaves, stem[verification needed] and root, namely DMT and 5-MeO-DMT.
This plant is famous for its movement of small lateral leaflets which rotate on their axis and jerk up and down with a period of about 3 to 5 minutes; this was likened to Morse code[verification needed], hence the common names. Charles Darwin in 1880 published his last work before his death, The Power of Movement in Plants, which describes this plant in detail.
