Rorídulas

Roridulaceae

Small South African family with a single genus (Roridula) and two species: R. gorgonias and R. dentata. Although they produce sticky mucilage and capture insects, they technically do NOT digest them directly — they do not secrete digestive enzymes. Instead, they maintain a symbiotic relationship with bugs (Pameridea) that digest the prey and whose excrement is absorbed by the plant. They represent a unique case of "proto-carnivory" or indirect carnivory.

Roridula

Roridula

Genus of 2 species (R. gorgonias, R. dentata) endemic to the Cape Province, South Africa. Shrubby plants up to 1.5 m with linear leaves covered in very long sticky trichomes. Although they capture insects like other carnivorous plants, they do NOT secrete digestive enzymes — insects are consumed by bugs (Pameridea roridulae) that live symbiotically on the plant and whose excrement is directly absorbed. This system of "indirect carnivory" via an intermediary is unique in the plant kingdom.
