Yes, I am sorry. I see you are trying hard. I wish you good luck in that endeavor.
You seem to have a lot of responsibilities on your shoulder. I do believe that the preservation of the Viking (species or complex hybrid) is in your hands. so please keep up the good work and try to preserve as many specimens of this beauty for future generations.
It is possible that in these islands you have three types of plants. Viking, thorellii and a hybrid between the two.
Just a thought.
The guy that I got the Nepenthes from in Bangkok is named
Chumpon Udomdun. There has been several articles on him and Nepenthes. One is from the Agriculture Techno Transfer Forum magazine 2/15/96. He had several types of the "Viking"
nepenthes amongst several other species from all over Thailand. I do have a couple of phone numbers from him about four years ago. Email me and I can send it to you if you want.
