Hutchinson, renamed the plant Dioncophyllum peltanum in 1927 ; surely it must "thank" H. K. Airy Shaw who ended these numerous naming in 1951 by naming the plant Triphyophyllum peltanum. It was recognised as carnivorous at some precise growth steps in 1979, by J. E. Marburger and T. L. Green. The greek origin of this name means: "three kinds of leaves".
