When Bruce and Clyde made the hybrid, they used a Nep that had been sent to Clyde from a collector in Cambodia, who collected the plants in the foothills of the Elephant Mountains not far from the town of Kampot.(Don't know about this spelling). In the same shipment, they also received plants of anamensis. According both of the guys, the anamensis plants were different from the kampotiana plants, but recent taxonomic revisions of the genus has kampotiana as a synonym for anamensis.
We have supposedly one of the few clones of kampotiana in our greenhouse, and to me, it is much closer to thorelii. We will soon have our website up with pictures of this plant. I knows there's others around, and would love to compare plants one day.
In the case of N. splendiana, Clyde's female kampotiana was the pod bearer, and the male maxima used is still around. Most of the kampotiana plants are long gone. After a period of good growth and blooming, they died off. It now seems they need a dry 'dormancy period' in late winter, along with cooler temperatures. Most of the plants were literally watered to death. They do have an unusual tuber-like rootstock, which supports the dry period needed to sucessfully grow them.
I'm sure one day this will all be sorted out. More detailed taxonomic work should be done in this very dangerous part of the world, but until then...
