About
The taxonomy of *Nepenthes junghuhnii* has been highly confusing since its discovery, with various authors suggesting it is a synonym of other species like *N. singalana* or *N. bongso*. It is characterized by strongly petiolate leaves and is considered a possible intermediate form between *N. sanguinea* and *N. singalana*.
Field notes
Morphology
The species is characterized by strongly petiolate leaves. The pitchers are described as being smaller than those of *N. sanguinea*, with a shape approaching that of *N. singalana*. The second plant mentioned in the historical text has a lower portion of a climbing stem with pitchers that differ from *N. sanguinea* only by the toothed interior margin of the peristome.
Distribution & habitat
Native to Sumatra, specifically collected in the Batak region of North Sumatra, near Lake Toba, and also associated with Mount Kerinci in the Sumatran province of Jambi.
History & etymology
The species was collected by Friedrich Franz Wilhelm Junghuhn between 1840 and 1842. The original naming by John Muirhead Macfarlane was never formally published, and Ridley's description using *N. singalana* specimens is considered a heterotypic synonym. B. H. Danser discussed the taxon in his 1928 monograph, noting it was based on plants collected by Junghuhn.
