Nepenthes argentii in habitat. Mount Guiting-Guiting, Sibuyan Island. Conservation status Scientific classification Kingdom: Plantae (unranked): Angiosperms (unranked): Eudicots (unranked): Core eudicots Order: Caryophyllales Family: Nepenthaceae Genus: Nepenthes Species: N. argentii Binomial name Nepenthes argentii
Jebb & Cheek (1997)[1]Nepenthes argentii (pronounced /nɨˈpɛnθiːz ɑrˈdʒɛnti.aɪ/, after George Argent) is a highland Nepenthes pitcher plant native to Mount Guiting-Guiting on Sibuyan Island in the Philippines. It is possibly the smallest species in the genus and does not appear to have a climbing stage.[1]
Nepenthes argentii inhabits subalpine shrubbery "with a smooth wind-clipped canopy 30 cm tall on an ultrabasic ridge".[2] It grows at an elevation of 1400–1900 m.[3]
On Mount Guiting-Guiting, N. argentii is sympatric with N. sibuyanensis at around 1600 to 1770 m.[1][4] A species resembling N. alata grows on Mount Guiting-Guiting at lower elevations of 800 to 1000 m.[5] Other plant species endemic to the mountain include Lobelia proctorii[6] and Rhododendron rousei.[7]
Nepenthes argentii has no known natural hybrids, although it may hybridise with N. sibuyanensis.[3] No forms or varieties have been described.
