“Memory” has been observed in the leaf closure of the insectivorous Venus flytrap (Dionaea muscipula). The rapid closure of the traps requires two stimuli within 30 s on the sensory hairs of their internal surface. We found that Dionaea has two endogenous chemical factors that induce the closure of traps without stimuli.
