Dear all:
I would like to say that i love to discuss these matters for months or years to come until we get a definite answer. We can't comprehend anything in absolute terms. If you remember that, then you'll be fine.
The main differences between the german giant and the hummer's giant is the T-ventral rib (the hummer's giant has a wider rib than the german, as well as the peristome (the peristome in the hummer's giant is thicker. I have also noticed that the average size of the hummer's giant is 10% larger than the german, but I guess, one will be closer to the truth, if we were to measure the average size of all the pitchers between the two types and then, make a comparison. I guess Jonathan is in a very good position to do this.
William: I have the large egg size pictures, but I am still waiting for my local cp society to publish the article on the net and I promised Julie Jones not to post it until the whole thing was published or posted somewhere. I was wondering if someone here can make room for the article on this website. I'll be more than happy to post it here, of course, if i am allowed to do so.
For the mycorrhyzal theories. i do believe they play a part in it, but as some of you may know, I am actually growing several cephalotus clones, and believe me, to have a large pitcher size cephalotus "typical" is very difficult. I am wondering if William's so called typical are in fact typical cephalotus. Nowadays, one must be careful with terminology. Julie Jones from the U.K. grows all her cephs under the same exact conditions, but then again, she says that there is only one giant ceph plant in her collection which still produces giant pitchers (genetics over environmental). Furthermore, when she got her giant ceph, she did not know it was in fact a giant form.
Therefore, it is very possible that one of William's typical cephalotus plants is a giant form and not typical. If it happened to Julie, it could have happened to William.
