Nepenthes murudensis is an ultra-highlander. It grows at high altitudes in its natural environment similar to those of  N. villosa. This species is slow growing! In Charles Clarke's book "Pitcher Plants of Sarawak" he has a profile of this species indicating that the lower pitchers are similar to N. tentaculata but without the bristles on the lid. As the plant puts out upper pitchers they begin to resemble N. reinwardtiana to some degree. The Nepenthes Nursery in Germany seems to be the only outlet for this species currently. I did get a plant labeled N. murudensis that was a Borneo Exotics clone, but that turned out to be a variety of N. tentaculata. I was fortunate to get a small rooted cutting from Exotic Plants Plus. I have found that the small tissue culture plants from the Nepenthes Nursery go through a stunted growth phenomenon after purchase. The growing tip seems to die and then the plant will put out some small sideshoots instead. This has happened with the 2 plants I purchased separately. I'm glad I got the cutting because it would take years to grow out the small TC plants to get decent sized pitchers.

Species variability: none that I'm aware of other than locality differences
$ / size: moderate; $25.00 and up
