Roridula is a South African genus of plants that, whilst having many of the adaptations of a carnivorous plant, such as the possession of insect-trapping sticky hairs, does not directly digest the animals it traps. Instead, it is mutualistic with a species of bug, Pameridea roridulae (a type of capsid bug), which feeds on the trapped insects. The plant obtains nutrients from the droppings of this symbiotic insect. Whether this plant is regarded as carnivorous or protocarnivorous is essentially a matter of style. The genus contains just two species, Roridula gorgonias and Roridula dentata, and is the only genus in the family Roridulaceae.
Roridula gorgonias:
Cephalotus follicularis, the only known species in this genus, is native to the extreme southwestern part of Australia (near the town of Albany) where it lives on the margins of freshwater wetlands, ditches, and slow streams. Plant size 4-6cm.
C. follicularis:
Heliamphora pulchella is endemic to the Chimanta group of Tepuis (Akopan Tepui) in Venezuela. The pitchers are only 3-4cm.
H. pulchella:
