It is a liana, with a three-stage lifecycle, each with a different shaped leaf, as indicated by its Greek name. In the first stage, T. peltatum forms a rosette of simple lanceolate leaves with undulate margins. It then develops long, slender, glandular leaves, resembling those of the related Drosophyllum, which capture insects; one to three of these leaves in each rosette.[1] The plant then enters its adult liana form, with short non-carnivorous leaves bearing a pair of "grappling hooks" [2] at their tips on a long twining stem which can become 165 feet (50 meters) in length and four inches (10 cm) thick.[3] T. peltatum is the largest of all confirmed carnivorous plants in the world, but its carnivorous nature did not become known until 1979, some 51 years after the plant's discovery.[4] Its seeds are about 3 inches (7.6 cm) in diameter, bright red in color, disc-shaped, with a peltate stalk emerging from the fruit. Most of the seed's development occurs outside the fruit.[5] The fruit and seed develop from an orange flower with five incurved petals.[6] As the seed dries out, its wide umbrella shape enables it to be transported on the wind.

Triphyophylum peltatum is currently cultivated in three botanical gardens: Abidjan, Bonn, and Würzburg. It is exceedingly rare in private collections.
