The only genus in the family Roridulaceae is Roridula.
Roridula is a small South African genus of evergreen, insect-trapping shrubs commonly called dewsticks or fly bushes. It contains two species, Roridula dentata and Roridula gorgonias, both endemic to mountainous parts of South Africa’s Western Cape. Their leaves and sepals carry numerous sticky tentacles that trap insects.
Roridula is unusual because it does not appear to digest prey directly in the way many carnivorous plants do. Instead, resident bugs in the genus Pameridea feed on insects caught by the plant. The bugs’ droppings provide nutrients that the leaves can absorb, creating an indirect plant–insect partnership.
The family’s classification has shifted over time: botanists once associated Roridula with groups including Droseraceae, Clethraceae, and Byblidaceae. Modern phylogenetic work recognizes Roridulaceae as its own family, with Roridula as its sole genus. Thus, the answer is a genus, not a species or family name.
