Abstract

Nepenthes maagnawense sp. nov. (section Alatae), restricted in the shrublands at 2300–2700 m a.s.l. in Mt. Maagnaw (Range, Bukidnon, Philippines), is here described. It differs from N. kitanglad in having terete non-angular climbing stem (vs. angular), inconspicuous pennate veins (vs. distinct), aerial pitchers that are broadest in the upper 1/3rd (vs. broadest in the lower 1/3rd), and a triangular aerial pitcher lid central basal appendage (vs. absent). The species is assessed as Endangered according to IUCN criteria. The population size is estimated to number fewer than 250 mature individuals. Known only from the type locality and probably site endemic to Mt. Maagnaw, Kitanglad Range, Lantapan, Bukidnon, Central Mindanao, Philippines.
