Nepenthes negros is a tropical pitcher plant native to the Philippines, specifically the islands of Biliran and Negros. [1] [6]

Nepenthes negros belongs to the informal "N. alata group", which also includes N. alata , N. ceciliae , N. copelandii , N. extincta , N. graciliflora , N. hamiguitanensis , N. kitanglad , N. kurata , N. leyte , N. mindanaoensis , N. ramos , N. saranganiensis , and N. ultra . [7] [1] [6] [8] 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. [7] [1]

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. [9]

<i>Nepenthes alata</i> Species of pitcher plant from the Philippines

Nepenthes alata is a tropical pitcher plant endemic to the Philippines. Like all pitcher plants, it is carnivorous and uses its nectar to attract insects that drown in the pitcher and are digested by the plant. It is highly polymorphic, and its taxonomy continues to be subject to revisions.

<i>Nepenthes copelandii</i> Species of pitcher plant from the Philippines

Nepenthes copelandii is a species of pitcher plant native to the island of Mindanao in the Philippines. Originally known from Mount Apo near Davao City and Mount Pasian near Bislig, it has since been discovered on a number of peaks throughout Mindanao. It may also be present on the nearby island of Camiguin. The species has a wide altitudinal distribution of 1100–2400 m above sea level. Nepenthes copelandii has no known natural hybrids. No forms or varieties have been described.

<i>Nepenthes graciliflora</i> Species of pitcher plant from the Philippines

Nepenthes graciliflora is a tropical pitcher plant endemic to the Philippines. Long considered a synonym of N. alata, it was restored as a separate species in 2013 by Martin Cheek and Matthew Jebb. It has been recorded from the islands of Bohol, Leyte, Luzon, Mindanao, Mindoro, Panay, Samar, and Sibuyan, and following the redelimitation of N. alata is the most widespread Nepenthes species of the Philippines. It is known from mossy, submontane forest, generally at 800–1,280 metres (3,000–4,000 ft) altitude, though the type specimen from Sibuyan was collected at only 300 m (1,000 ft).

<i>Nepenthes hamiguitanensis</i> Species of pitcher plant from the Philippines

Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1200–1600 m above sea level. Once thought to be a natural hybrid between N. micramphora and N. peltata, this plant is now considered a species of possible hybridogenic origin. It produces squat upper pitchers that vary greatly in pigmentation, from red speckled to yellow throughout.

<i>Nepenthes ceciliae</i> Species of pitcher plant from the Philippines
