Nepenthes is only distributed in Truss Mountain in Madi, and has not been regarded as an independent species for a long time. Shortly after it was discovered, people thought it was the same species as N. villosa, which is endemic to Mount Kinabalu. In the Nepenthes in Lushan written by Shigeo Kurata1976, he wrote: homeland.

"Madi Mountain in Therus is located in the south of Lushan Mountain in Kinabad, where Nepenthes originated. Although this has not been confirmed, its existence can be expected, because there is an altitude suitable for the growth of this pitcher plant. "

Later, Nepenthes macrophylla was considered as an individual of Nepenthes eduarda, and it was closely related to it. Nepenthes was first discovered by Johannes Marabini in March 1983. He also collected the type specimen with the number of Marabini 2 167, which is now kept in Herun-Nuremberg University. Four years later, Marabini classified it as a new subspecies of Edward.

Discussion on species nomenclature and origin

In the book Nepenthes Borneo published by Anthea Phillipps and Anthony Lamb in 1996, Nepenthes Borneo was described and named "Nepenthes (Marabini) Jebb &; Check it out. Botanists Matthew Jebb and Martin Cheek plan to upgrade Nepenthes to an independent species in 1994, and discuss their views in their paper 1997. Charles Clarke also supported this view, pointing out that Nepenthes and Nepenthes tomentosa are more similar to Nepenthes than Nepenthes and Nepenthes macrophylla, but Nepenthes and Nepenthes tomentosa have been divided into two parts.
