N. alata'', ''
N. ceciliae'', ''
N. copelandii'', ''
N. extincta'', ''
N. graciliflora'', ''
N. hamiguitanensis'', ''
N. kitanglad'', ''

''European Journal of Taxonomy'' 69: 1–23. ][Cheek, M. & M. Jebb (2013). ''Nepenthes ultra'' (Nepenthaceae), a new species from Luzon, Philippines. ''Blumea'', published online on October 24, 2013. ] These species are united by a number of morphological characters, including winged
petioles,
lids with basal ridges on the lower surface (often elaborated into appendages), and upper pitchers that are usually broadest near the base.
It has been suggested that ''N. negros'' might fall within the natural variability of ''
N. ramos'', though field studies would be needed to confirm this.
