Action potential and contraction of Dionaea muscipula (Venus flytrap).
Observation of the action potential and contraction of the leaf of Dionaea muscipula Ellis revealed several interesting phenomena. Two successive stimuli are generally necessary to cause contraction. The first and ineffective stimulus is associated with slow depolarization. The second stimulus has much more rapid depolarization and initiates contraction.
