Codariocalyx motorius

About

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