Nepenthales (Nepenthales Bercht. & J.Presl) is an order of carnivorous flowering plants in the Cronquist system of plant classification.
Taxonomy
The order Nepenthales as of 2018 is a clade within Caryophyllales and contains the following families:
Carnivorous Nepenthales

Non-carnivorous Nepenthales

Evolution within Nepenthales
Common traits of the Nepenthales include the presence of glandular hairs or active secretory tissues. The presence of these glandular hairs and secretory tissues is believed to be important to the evolution of carnivory within Nepenthales. Carnivory within the Nepenthales is believed to have only evolved once with the carnivorous lineage diverging from the rest of the Nepenthales around 95.1Mya in the late Cretaceous.
