    Well I always assumed the tendril evolved first, since it is a feature that is shared with other plants, and it seems like the plant would need it more at first to climb above/get support from competing foilage in the tropics; Then the pitcher would come later to give the plant more of an edge. But I know comparatively nothing on either evolution or biology.

    If you follow the theory of punctuated equlibrium the pitcher and tendril appered very quickly with little or no transitional forms. Gradualism states that random, accidental changes slowly lead to something like a pitcher.

    Yeah you do have a good point, krueger. But I wasn't exactly trying to say exactly how it happened, I was just sort of pouring stuff outta my mind and writing it down.

    But, if you look closely at xvart's second picture, the pitcher in focus (at 12 o'clock) has its wings fused with the leaf edge. That makes me think that that is how wings may have developed earlier on. Also, the leaf edge has hairs not unlike the hairs on the wings.

    I dunno, once again I could just be blabbing.

    JC. I have seen this on other seedlings I have had. The plant grows out of it as it matures unfortunately and starts growing tendrils.

    All my gracilis seedlings were doing that until I killed them recently. I know I am a bad grower lately. Any how I assumed they would grow out of it.

    I look forward to seeing your plants as they grow.
