These are plants in which rapid movement of the plant is involved in capturing prey.
Caltha dioneaefolia, which grows in Tierra del Fuego in Argentina, was first described by Dr. Hooke in 1874. He wrote "Delpino, for example, has suggested that a plant, first described by myself from Tierra del Fuego—Caltha dioneaefolia—is so analogous in the structure of its leaves to Dionaea that it is difficult to resist the conviction that its structure is also adapted for the capture of small insects." Another plant, Molinia coerulea, is a grass whose flowers have bracts which act as the jaws of a spring-type trap and can capture insects for a period of time during flowering.
