Summary

The uptake of organic matter by the insect-trapping glandular leaves of the Western tropical African liana Triphyophyllum peltatum (Dioncophyllaceae) is demonstrated for the first time. After feeding carbon-13 labelled L-alanine to the trapping leaves, the label is detected in apical shoot parts and normal (non-trapping) leaves within 2d of application. With this proof of resorption and transport, the carnivorous syndrome of I. peltatum is demonstrated to be complete. The prey composition reveals the glandular leaves of I. peltatum to be traps for flying insects, predominantly.
