    Very interesting. [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img] And gross. lol Maybe the bracts secrete a type of insecticide to keep pests from reaching and eathin the flower?? Have you ever noticed anything munching on the flowers themselves?

    Its a very pretty plant though...the bracts are quite nice.

    Hi all,

    just found some plants at a beach nearby. These seem to be way more sticky and were loaded with dead insects (dark spots on the image).



    Plants were growing almost on the beach in a very saline Mangrove habitat.

    Thats interesting. There is a reason for everything in nature so that feature must benefit the plant in some way even if just a protective device. But I wonder why just that one species of passiflora has the sticky bracts. I wonder if the sticky stuff has some natural insecticide in it.

    Thanks for the pic. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img] I still want to get one of those. They might have them at Loggees.

    Hi. Mybe you can boile an egg and put some of the white part of it(wich is protein) on the sticky part and see if it disolves it. If it does it might get a clearer prespective about the Carnivorous or not nature of the plant...

    Well, that plant is on the beach and I am not anymore [img]http://www.**********.com/iB_html312/non-cgi/emoticons/sad.gif[/img]. I brought however a cutting and will try it in my garden. Although it is rooting already, it will take some time to flower. Anyway, according to the article cited by Vic the presence of Protease is already proofen. That's already more carnivory than for Darlingtonia!
    I might anyway try your egg white suggestion, but yah - later [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img] Not sure if it would work outdoors (heat, sun, rain, ants, geckos etc.)

    PS: There are some traces on the web that P.foetida has been 'renamed' to P. arida. Can somebody confirm this officially?

    Update: According to Hartmeyer/Schlauer the research methods of Radhamani TR; Sudarshana L; Krishnan R. proofing digestive enzymes in P. foetida were inappropriate. Their own research didn't reveal any digestive enzymes.

    Wow...that must have taken some digging to get that info. Thanks Volker. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img] I guess that should put an end to that speculation.

    Well, not really that much digging [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img] . There is a similar P. foetida thread on the website of the German carnivorous plant society and I am just trying to synchronize both threads to have coarsely the same information in their respective languages.
    According to Mr. Hartmeyer the mentioned research is not credible for the reason that the plants had been fed with refridgerated ants. Since the ants contain digestive enzymes themselves, the tests will most likely turn out positive. The other fact is the type of glue that resembles the resin-style glue as it is found in Roridula and prohibits the function of enzymes.
