Hi everyone :)

When I was visiting Ellison he showed me some of his tropical pitcher plants that have fangs on the hoods, and explained that no one is really sure why they have fangs.

I thought about it and came up with a theory:

If a small lizard or frog or large bug fell into the pitcher and tried to jump out, the fangs would keep them from jumping out by poking them, causing pain, resulting in the natural reaction of moving away from the pain, back into the pitcher.
The fangs may be a way for the plant to keep things in the pitcher and not allow them to jump out.

Just a thought, I could be wrong, Im not an expert or anything :-))
 
yeah---that was an old hypothesis....
here's a newer one:
we know know that Nepenthes bicalcarata shares some sort of symbiotic relationship with ants that live in its vines....the fangs hang precariously over the center of the pitcher...they also produce copious amounts of nectar. ants try to feast near these sites end up falling in.

from a mechanical engineering point of view, the fangs may also serve as reinforcement gussets for the opening
 
There is amphirion's hypothesis which is widely accepted as plausible. (I've seen it happen as well, though not with the specific symbiotic ant species, of course)

Then there is another theory that suggests that maybe the fangs also act as a defense against tree shrews, monkeys or other small mammals that would try to raid the pitchers of their contents. For instance when the animal pokes its head inside, it gets a nasty pinch on the top if it's head, giving it incentive to move on up the mountain and find some promiscuous Nepenthes lowii to gobble upon instead.

Then, the one reality we can be sure about, is that Nepenthes bicalcarata fangs mesmerize endless amounts of humans to no end, thereby influencing us to propagate the species through tissue culture, seed, leaf cuttings, etc. Sometimes even going to great lengths to make sure that the plants are provided with unreasonably warm and humid conditions that defy the local climates of the continents that the plants are now able to call home.

Cool!

A bunch of theories, all very plausible.

I like it!

;)

Nepenthes bicalcarata wants to rule the world...

Last Summer, my Nepenthes bicalcarata lived outside. There were sugar ants creeping along the entire plant and feeding off the nectar, always. I can say the pitchers were quite full of the lazy ones too :p It's probably a mix of Jon's theory, and Dex's. If the pitchers are so absolutely full of ants, it'd undoubtedly be an easy target for anything larger wanting an easy meal. However, if it weren't for the fangs, the ants would likely not be falling into the pitchers in such numbers either.

It's an interesting mystery ;) But regardless of the reason, it *is* gonna take over the world :p

You guys crack me up!

I think youre right, I think there are several uses/reasons for the fangs, and they all make complete sense to me.

They sure are pretty plants....

;D

Plants (and animals) adapt to their environment according to various needs: defense, aggression, food, camouflage, symbiosis,... It's a plant eat animal world out there!

LOL!

Well, as long as I dont hear "FEED ME!" in the middle of the night....

Has someone been reading Michael Pollan's "Botany of Desire"?

Some kind of abuse I guess...

ROFL!

I saw jurows reply about the botany of desire, then read jims reply about some kind of abuse, and sat here wondering what on earth that meant ;)

I finally figured it out :D
