Evolution of Nepenthes pitcher plants.

Well, the gross morphology of plants is very flexible. These, for example, are all the same species. Could you go into more detail as to what is giving you a hard time?

I'm guessing that you know more about sundews and pitcher plants than I do. I'd stop posting on this thread, except that you've got me kind of interested.Could you supply some pictures and/or diagrams, along the lines of "this is a basal sundew, this is a pitcher plant, this is what an intermediate form would look like and you can see why it wouldn't work"?I looked it up on WP and it says that some pitcher plants are derived from fly-traps rather than directly from basal sundews. I don't know if this is of any use to you because at this point I don't know what would be.

Interesting, but I think that that might have worked the other way round from the way that I think that you're thinking.In any case, the question is about gross morphology.
