荷属东印度群岛的猪笼草科植物
In his monograph of 1908, "Nepenthaceae", John Muirhead Macfarlane placed "N. sumatrana" in synonymy with "N. treubiana", a species native to New Guinea. B. H. Danser supported this interpretation in his seminal monograph, "The Nepenthaceae of the Netherlands Indies", published in 1928.
