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.^[3] 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.^[2]

Plant taxonomy systematists currently favor the APG IV system of 2016 over the older Cronquist system for classifying flowering plants (Angiosperms).

The 2009 APG III system assigned the first two families to the order Caryophyllales and the last family to the order Ericales.^[4]
