About
Nepenthes mapuluensis (; from Mount Ilas Mapulu), the Mapulu pitcher-plant, is a species of tropical pitcher plant native to East Kalimantan, Borneo. It is known only from a restricted geographical range and is listed as Endangered on the IUCN Red List.
Nepenthes mapuluensis has no known natural hybrids. No infraspecific taxa have been described.
How to grow it
Nepenthes mapuluensis is extremely rare in cultivation. It has been artificially crossed with N. ventricosa to produce the hybrid Nepenthes × mapulucosa Hort.Westphal in sched. (2000), although this name is a nomen nudum.
Where it grows
The type locality of N. mapuluensis is described on the original collector's label, which reads: "the species is common on the limestone mountain of Ilas Mapulu at an altitude of 800 m". The population from which the type specimen originated was subsequently destroyed and for some time the species was thought to be extinct. More recently, however, further observations of N. mapuluensis have been made by Troy Davis, Joachim Nerz and Andreas Wistuba, significantly expanding the known range of this species. This being the case, N. mapuluensis is thought to be endemic to the Sambaliung mountain range in East Kalimantan.
