Abstract
A new endemic species, Nepenthes cabanae, belonging to sect. Insignes is described from the Mt. Pantaron range of central Mindanao. The species is assessed as Critically Endangered. This discovery brings the number of Nepenthes species in this mountain range to eight. Mt. Pantaron is currently not a protected area, but the diversity of Nepenthes taxa suggests concerted efforts should be made to develop a conservation strategy to preserve and protect the area.

Nepenthes cabanae Lagunday & V.B. Amoroso, sp. nov.
Diagnosis: Leaves unequally decurrent with four longitudinal nerves; lower pitchers subcylindrical, bottom half slightly inflated, top half cylindrical towards the mouth; peristome with
short triangular indistinct teeth not projecting beyond peristome
margin.
Etymology: The specific epithet honors Dr. Veneracion G.
Cabana, who funded scientific expeditions in the unexplored
areas in central Mindanao, Philippines viz. Mt. Pantaron range
and Mt. Tangkulan range.
Conclusion And Recommendation:
Explorations in the incompletely surveyed areas of central
Mindanao, Philippines led to the discovery of N. cabanae
another new species of pitcher plant making the Philippines
home to a total of 58 species. This discovery makes the Mt.
Pantaron range a home to eight Nepenthes species. Mt. Pantaron
is currently not a protected area, and the presence of threatened
and endemic species of Nepenthes in the area calls for
immediate conservation strategies by the local stakeholders to
preserve and protect these plants from illegal poaching.
