Nepenthes ramos Jebb & Cheek, sp. nov. is described and illustrated from Surigao Province, Mindanao, Philippines, and placed in the N. alata Blanco group. An updated key to the species of the group is provided. The new species is characterized by the subcylindric upper pitchers which are more or less equally wide at base and apex, only slightly and gradually constricted in the middle and lacking in fringed wings, and by the lower surface of the lid having a well-developed basal appendage almost lacking glands, the lid surface having dimorphic nectar glands, large perithecoid glands along the midline and much smaller non-perithecoid but bordered glands on the rest of the lid. The species is assessed as Critically Endangered using the IUCN 2001 standard. Logging and open-cast mining are thought to be threats to this species.
