Nepenthes harauensis Hernawati, R.Satria & Chi.C.Lee. spec. nov.
Nepenthes harauensis has several morphological characteristics similar to N. bongso, but the pitcher shape is more like the N. singalana. The most prominent distinguishing character is the thick and stiff coriaceous leaf structure, the peltate tendril insertion, and the sheath-like petiole, which clasps the stem for ¾– ½ of its circumference.
Distribution. Nepenthes harauensis is only known
from the type locality in Harau, West Sumatra,
Indonesia.
Etymology. The specific name refers to the place “Harau,” a sub-district of Lima Puluh Kota Regency.
