International Carnivorous Plant Society


The International Carnivorous Plant Society is a non-profit organization founded in 1972. It is the International Cultivar Registration Authority for carnivorous plants. As of June 2011, the society had around 1400 members.
The ICPS is probably best known for its quarterly publication, the Carnivorous Plant Newsletter.

Conservation efforts

The ICPS has set up the Nepenthes clipeata Survival Project to facilitate ex situ conservation of this species. With only an estimated 15 plants remaining in the wild as of 1995, Nepenthes clipeata is the most endangered of all known tropical pitcher plants. It is estimated that there are only three or four genetically-distinct lines of "white market" plants in cultivation.
The ICPS partially funded the establishment of The Rare Nepenthes Collection, which aims to conserve four of the rarest Nepenthes species: N. aristolochioides, N. clipeata, N. khasiana, and N. rigidifolia.
