Nepenthes argentii

Nepenthes argentii (/nɪˈpɛnθiːz ɑːrˈdʒɛntiaɪ/; 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.[2]

Nepenthes argentii inhabits subalpine shrubbery "with a smooth wind-clipped canopy 30 cm tall on an ultrabasic ridge".[1] 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.[2][4] A taxon resembling N. alata grows on Mount Guiting-Guiting at lower elevations of 800 to 1000 m;[5] it was described as N. graciliflora by Adolph Daniel Edward Elmer.[6] Other plant species endemic to the mountain include Lobelia proctorii[7] and Rhododendron rousei.[8]

Nepenthes argentii has no known natural hybrids, although it may hybridise with N. sibuyanensis.[3] No forms or varieties have been described.
