Nepenthes extincta

Nepenthes extincta is a tropical pitcher plant native to the Philippines. It is known only from Surigao del Sur, Mindanao, where it has been recorded at altitude.
This species belongs to the informal ""N. alata" group", which also includes "N. alata", "N. ceciliae", "N. copelandii", "N. graciliflora", "N. hamiguitanensis", "N. kitanglad", "N. kurata", "N. leyte", "N. mindanaoensis", "N. negros", "N. ramos", "N. saranganiensis", and "N. ultra". 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.
The specific epithet "extincta" was chosen to indicate that this species may already be extinct in the wild. "Nepenthes extincta" is known from a single herbarium specimen collected in 1978.
It has been suggested that the only known specimen of "N. extincta" might represent a natural hybrid between "N. merrilliana" and "N. mindanaoensis", as both of these species grow near the type locality of "N. extincta" and share many morphological features with it.
