Codariocalyx motorius

Species of legume

Codariocalyx motorius, known as the telegraph plant, dancing plant, or semaphore plant, is a tropical Asian shrub in the pea family (Fabaceae), one of a few plants capable of rapid movement; others include Mimosa pudica, the venus flytrap and Utricularia. The motion occurs in daylight hours when the temperature is above 72 °F (22 °C). Many sources claim that the two leaflets move on a common axis even though there is no rigid connection between them.
