About the Image

Left: Trigger hair of Dionaea muscipula (Venus flytrap). Right: Enlarged view of mucilage-covered tip of Drosera capensis (Cape sundew). Each of these two different structures produces an electrical signal that triggers leaf movements, an apomorphy uniting Dionaea and Drosera with the Droseraceae.
