Nepenthes philippinensis formed dense mats on the exposed rocks of the cliff tops and at the forest edge in mull-ridge, gap, upper montane rainforests and dry-peak forests from the Mt. Pulgar (Thumb Peak)/Mt. Beaufort area to south of Mt. Victoria. Nepenthes philippinensis was abundant over 600m, particularly as a terrestrial exposed to the full sun. It was particularly abundant in the Mt. Victoria area. Hanging pitchers tended to be green and elongated, while the ground pitchers were red and fatter. Flowering plants were often seen.
Time restricted the team visiting the areas we knew were interesting, and many years later turned out to be the home of two of the world's largest Nepenthes, N. palawanensis and N. attenborough.
