Carnivory on demand: phosphorus deficiency induces glandular leaves in the African liana Triphyophyllum peltatum.

Triphyophyllum peltatum, a rare tropical African liana, is unique in its facultative carnivory. The trigger for carnivory is yet unknown, mainly because the plant is difficult to propagate and cultivate. This study aimed at identifying the conditions that result in the formation of carnivorous leaves.
