Nepenthes thorellii in Thailand , Laos and Cambodia 
N. mirabilis and N. thorelii are two well-known species on Thai Nepenthes markets. But the names used on local markets and scientific names are very confused for Nepenthes enthusiasts who try to classify these plants scientifically
On Thai markets esp. at Chatuchak, the most famous weekend market, you could find both local and imported Nepenthes. displayed on pathway stands, and most local Nepenthes found were mainly N. mirabilis and N. thorelii with occasionally N. ampullaria (green) . There was also one unidentified species that was called "Viking" with sometimes classified by some retailers as N. rafflesiana.
Thorelii - Mirabilis and unidentified spp. in Thailand
It would be so kind if you could correct scientific names of these Nep. and mail to neo1@neofamthailand.com
Thank you for your contribution.

There are at least three type of N.thorelii in Thailand
This first one is called N.thorelii "Tiger" | |
| |
|
|
The second is N.thorelii "Cambodia"
with paler and more belly pitchers | |
| |
|
|
|
|
Both types have long narrow leaves
These are Tiger leaves |
These are Cambodia leaves | |
|
|
|
|
Look inside theTiger pitcher |
Cambodia pitcher | |
|
|
|
|
theTiger pitcher is a little bit slimmer and smaller with shorter tendril |
while Cambodia pitcher is a little bit belly so it tends to lie horizontally . Tendril is also longer . | |
|
One major identification point |
This pic. shows one important point to differentiate Tiger from Cambodia | |
|
|
|
|
Tiger >>>> less pitchers |
Cambodia usually produces more pitchers and last longer so worthy to collect | |
|
|
There is also Tiger subtype 'Brilliant Red" which is rare. |
|
|
Even flowers are red , to compare with the common thorelii | | |
  |
|
|
Picture of the third type thorelii "Laos Tiger" |
These are upper Red Tiger :Thai subvar. from Phang-Nga |
|
Notice Upper Red Tiger(Thai)
easily produces red pigments. |
Upper common thorellii |
|
N. thorellii (Red Tiger) babies produce red pigments very soon after seedling , promising of brilliant red pitchers in the future |
To compare with common thorellii. | |

New Idea : Nectar glands compare
Marcello Catalano (http://www.nepenthesofthailand.com/) gave me an idea to try identify Nepenthes spp. by their nectar glands morphology and arrangement or distribution underlid. I don't know if this method will work , but I decide to try . I use stereomicroscope to explore the nectar glands of each spp.May be the mysterious of Viking will become a legend in months.
Let me start with pitcher plants that Thai recognized for a long time as Nepenthes thorelii.
