For the sake of knowledge, here is a list of the Nepenthes species of Indochina, with the general details that you're probably looking for. Click on the name of the Country to see a map of distribution.
N. ampullaria: not common at all, it's only known from a few locations at the border with Malaysia and a few others in the Songhkla province.
N. andamana: a new species from the coastal savannahs of the Phang-nga province. It often produces hybrids with N. mirabilis in the wild, and a huge number of hybrid seeds and plants entered in cultivation simply nicknamed N. “tiger Phang-nga”, “giant tiger” etc. Close to extinction within the Country. Closely related to N. suratensis. Description. Photo. Wikipedia.
N. chang: a new species from the mountains of the Trat province, where it grows at 300-600 mt, on steep and peaty soil, in partial shade. No other species grow at the same locations. Closely related to N. kampotiana. Description. Photo. Wikipedia.
N. gracilis: not common at all, it's only known from a few locations at the border with Malaysia and a few others in the Songhkla province.
N. kampotiana: a beautiful species from the coastal savannahs of the Trat province. In at least one colony, the hybrid with N. mirabilis was relatively common. It entered in cultivation a N. “tiger Trat”. Nepenthes geoffrayi is a synonym. Close to extinction within the Country. Description.
N. kerrii: a new species from the Satun province, where it grows in savannahs at about 500 mt altitude. Following my request, it was nicknamed “sp. Trang” on Stewart MacPherson's “Pitcher Plants of the Old World”, even if it has nothing to do with the Trang province. It also entered in cultivation as “sp. Satun”. No other species grow at the same locations. Closely related to N. kongkandana. Description. Photo. Wikipedia.
N. kongkandana: a new, still unpublished species from the lowlands of the Songkhla province. Of the three colonies explored, just in one case N. mirabilis was present, and only one, little hybrid plant was found. It entered in cultivation as N. “tiger Songkhla”. Close to extinction within the Country. Closely related to N. kerrii. Report (Hat Yai).
N. mirabilis: very widespread all over the southern region, it can also be found in the north and north-east of the Country. Much less abundant than it was a few years ago, being the most common and easy to find, it's also the main victim of poachers.
N. mirabilis var. globosa: a new variety from the Phang-nga and Trang provinces, where it grows at sea level. In Phang-nga, this variety doesn't seem to produce hybrids with the typical N. mirabilis. In the Trang province, the two varieties never grow together. It entered in cultivation as N. “Viking”, N. globosa and N. “Trang bizarre”. It was also called “sp. Phang-nga” on Stewart MacPherson's “Pitcher Plants of the Old World”. Close to extinction within the Country. Report (Trang). Report (Phang-nga). Description.
N. sanguinea: it can only be found on the mountains of the Yala province, at the border with Malaysia.
N. smilesii: a very widespread species that grows on the sandstone tableaux of the North-Eastern region, called Isaan. It can be found from 200 up to 1300 mt. No other species grow at the same locations. Nepenthes anamensis is a synonym. Report (Phu Kradung). Description. Wikipedia.
N. suratensis: a new species from the coastal savannahs of the Suratthani province. No other species grow at the same locations. It entered in cultivation as N. “tiger Surat”. Close to extinction within the Country. Closely related to N. andamana. Description. Photo. Wikipedia.
N. thai: a new species recently described by Martin Cheek, it grows on the mountains of the Narathiwat province, at the border with Malaysia, at about 500 mt altitude. It entered in cultivation with the nickname “sp. Narathiwat”. No other species grow at the same locations. Closely related to N. benstonei. Description. Photo.
Hybrids: on the market you might find many hybrids called N. mirabilis x “tiger”. First of all, make sure that the seeds of these hybrids were taken from the wild, otherwise they could be anything. Then, we only have two species that often grow together with N. mirabilis and readily produce hybrids with it: N. andamana (Phangà Province) and N. kampotiana (Trat Province). So, as long as you know the province of origin, you know what hybrid you have.
CAMBODIA
N. bokorensis: a very attractive new species, recently described by François Mey. It grows on Phnom Bokor, a 1000 mt sandstone tableau in the south of the Country. Report (Phnom Bokor). Description. Wikipedia.
N. kampotiana: Kampot, a city in the south, is the place that gives the name to the species. The distribution of this plant continues from the coast of the Trat province in Thailand, along the Cambodian coast, to end up on the coast of southern Vietnam.
N. mirabilis
N. smilesii: the Cambodian colonies of this species have been found in the south of the Country, from sea level up to 800 mt. Report (Kampot). Report (Kirirom).
VIETNAM
N. kampotiana: the south of the Country is the western end of its distribution, still limited to coastal, sandy savannahs.
N. mirabilis
N. smilesii: here is where its synonym, N. anamensis, was first found and described, on the Annamite Range, near Dalat. The species has been reported to grow in both central and southern Vietnam, up to 1500 mt.
N. thorelii: lost since 1908 and never introduced in cultivation, the origin of the whole “indochinese mess” has been recently re-found, after 100 years, by some local Nepenthes enthusiasts, just a few km from the type location. Its distribution seems to be limited to the south of the Country, where N. kampotiana ends. Description. Wikipedia.
