species Rorídulas
Morphological Summary
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.
Distribution Endemic to the Cape Province, South Africa: fynbos and acidic sandy soils, Cedarberg and Hexriver Mountains. Very restricted distribution.
Conservation Vulnerable. Very restricted distribution; threatened by invasive exotic plants (Acacia), excessive fire, and collection. Protected by South African legislation.
