Related Species
Nepenthes mapuluensis is very similar to N. northiana and there is some question as to the validity of its species status. Although there are few morphological characters separating these two taxa, there seem to be several stable differences that can be used to distinguish between them. Compared to N. northiana, the leaves on the climbing stems of N. mapuluensis are more linear, the pitchers darker in colour, and the upper pitchers narrower. It is also worth noting that N. northiana is known only from the Bau area of Sarawak, which lies several hundred kilometres away from the only known populations of N. mapuluensis.
In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. mapuluensis as a possible synonym of N. northiana.

Famous quotes containing the words related and/or species:
“No being exists or can exist which is not related to space in some way. God is everywhere, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an effect arising from the first existence of being, because when any being is postulated, space is postulated.”
—Isaac Newton (1642–1727)
“The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.”
—Rebecca West (1892–1983)
