Nepenthes of Indochina
N. ampullaria (TH)

N. benstonei (TH): N. thai is a synonym.

N. bokorensis (KH)

N. chang (TH, KH)

N. gracilis (TH, KH)

N. holdenii (KH): possibly a synonym of N. chang. The two species grow on the opposite sides of a mountain range, more colonies in between need to be seen to draw conclusions.

N. kerrii (TH, MY): for the moment, I put here all the confusing species from the peninsula: N. andamana, N. kongkandana, N. krabiensis, N. suratensis, N. hirtella, N. bracteosa, N. ridzaiana.

N. mirabilis var. globosa (TH): the so-called N. sp. Viking from Trang.

N. mirabilis var. mirabilis (TH, KH, LA, VN)

N. orbiculata (TH): the so-called N. sp. Viking from Phang Nga.

N. rosea (TH): the only Nepenthes with a rosette growing on the peduncle!

N. sanguinea (TH)

N. smilesii (TH, KH, LA, VN): N. anamensis, N. geoffrayi and N. kampotiana are synonyms (see Catalano, 2017 - in Italian). 

N. tayninhensis (VN): the hairy plant from Lo Go-Xa Mat thought to be N. thorelii (see Catalano, 2017 - in Italian).

N. thorelii (TH, KH, VN): the glabrous plant from the coasts of continental Indochina thought to be N. kampotiana (see Catalano, 2017 - in Italian).
