Nepenthes junghuhnii
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.
