I seem to recall a professor from a university (in Wisconsin?) - I think Gibson was his name... writing an article in CPN showing his small rajah plants. A couple years later, I also seem to recall him asking thousands of dollars for the same plant/s, which were quite larger. I hope that if they were sold the proceeds went to the university!! Then, I think the same person had Heliamphora tatei, or was it neblinae?
Anyway, the point I was going to make was that there was once a time, not so long ago, when N rajah and other rare plants were not available everywhere and were a lot more expensive than they are now, if you could even find them!
Heck, $5000 in the 80s could have bought you all of Mt.Kinabalu! (That was a joke)
