ScienceDaily (Nov. 15, 2010) — A new species of carnivorous pitcher plant has been found by Fauna and Flora International (FFI) in Cambodia's remote Cardamom Mountains. The discovery of Nepenthes holdenii is an indicator of both the stunning diversity and lack of research in the forests of the Cardamom Mountains.
The large red and green pitchers that characterize Nepenthes holdenii are actually modified leaves designed to capture and digest insects. The pitchers can reach up to 30 centimeters long. The carnivorous strategy allows the plants to gain additional nutrients and flourish in otherwise impoverished soils.
A further unusual adaptation seen in this new species is its ability to cope with fire and extended periods of drought. Cambodia's dry season causes forests to desiccate and forest fires are common. Nepenthes holdenii exploits the clearings caused by these regular blazes by producing a large underground tuber which sends up a new pitcher- bearing vine after the fires have passed.
