Roridula


Roridula (/rɒˈrɪdjʊlə/; from Latin roridus "dewy") is a South African genus of plants restricted to the Cape Provinces. Its distribution is threatened due to the farming of rooibos. While 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 has a mutualistic relationship with Pameridea roridulae, a species of capsid bug, which lives on the plant and 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 semantics. The genus contains just two species, Roridula gorgonias and Roridula dentata, and is the only genus in the family Roridulaceae.
