Following the discovery of Nepenthes attenboroughii on Mount Victoria, I returned to Palawan in January 2010 to explore another mountain called Sultan Peak with a Filipino botanist friend. As mentioned in my article on Nepenthes attenboroughii one year ago, the Philippine island of Palawan is of extreme botanical interest because it is a hotspot of diversity located close to the great island of Borneo, but it has remained relatively little explored, especially in terms of carnivorous plants.
