Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Nepenthes rhombicaulis faces significant pressure from habitat destruction due to agricultural expansion and infrastructure development in its limited montane range. Mining activities and quarrying operations pose additional threats to the specialized ultramafic soils this species requires. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change threatens to alter the specific temperature and humidity conditions of its high-altitude habitat.
Habitat
This carnivorous pitcher plant is endemic to ultramafic soils in montane forests of Palawan, Philippines, typically found at elevations between 1,200-1,600 meters. It grows in mossy forest environments with high humidity and specific soil chemistry requirements associated with serpentine substrates.
