This is an original print from Rumphius' Herbarium Amboinensis, Vol.5, published in 1747. It is deposited in Paris Herbarium. It has probably been drawn in the late 1600's. The plant on the far right is a species of Flagellaria (according to Phillips and Lamb's Pitcher-Plants of Borneo) François Mey.

It has been stated several times that some species from what has been called "Indochina" develop a rootstock in order to survive the dry period that most parts of Cambodia, Vietnam, Laos and Thaïland endure. In Cambodia for exemple, april and may are very hot months ( average temperatures are beyond 30s °C) and the rain only comes back for good in june. See climate chart for Phnom Penh here: en.wikipedia.org/wiki/CambodiaIn their Skeletal revision of Nepenthes (1997), Jebb and Cheek wrote about Nepenthes thorelii: "a plant of seasonnally dry grassland, surviving as a dormant roostock during the dry season when fires burn out the above ground vegetation". See the rootstock of a Nepenthes smilesii specimen from Paris herbarium: www.lhnn.proboards107.com/index.cgi?action=display&board=herbarium&thread=1258&page=1See also this page where Dave Evans shows pictures of Nepenthes anamensis roots: www.rci.rutgers.edu/~dpevans/Nepenthes/N_anamensis.htm#MichaelI have often read that growers and hobbyists refer to those rootstocks as "tuber roots" but more research need to be done to check the accuracy of this word. Here is a list of the rootstock species: - Nepenthes thorelii; - Nepenthes smilesii (probably conspecific with Nepenthes anamensis, my friend Marcello Catalano will clear that for good); - Nepenthes bokorensis; - The "Tiger" and "Giant Tiger" sold by Neofarm, though their status have to be cleared; - Nepenthes sp. "Viking"; Note that those plants (thorelii and smilesii) have not been formally classified as a taxonomic group.Please, also note that this is just a provisional list. Some of us (especially Marcello Catalano) are currently working on those Indochina species and more plants are being discovered, though their status will have to be cleared too. I have included Nepenthes bokorensis in this list but the presence of a rootstock has to be definitely proved. More field research and examination of cultivated material should quickly provide the answer. I did not manage to check the roots of Nepenthes bokorensis but I do include the species in the above list for a few reasons: - its taxonomical relation with Nepenthes thorelii, smilesii and sp. "Viking"; - the presence of a very dry season in Cambodia; - and, most of all, the presence of Drosera peltata, a very well known tuberous Drosera, living along with Nepenthes bokorensis . See this picture: Please, post in this thread pictures of any above species rootsystem you may have. François Mey.

Adult plants: The following plant grew in shade. The leaves are broader. Aerial pitchers: Lid: -Peristome: - under the lid. A very colorful spot with lots of glands, mainly located in the center: Spur: A raceme. Some inflorescences have some flowers borne on double pedicels like those of Nepenthes sanguinea but this is an irregular feature. I found most flowers are developped at the end of a single pedicel like most Indochina species ( smilesii/ anamensis, mirabilis, the dubious thorelii). And these are some seed pods:
