    Whenever there are ID pics of the two, and the size perspective isn't obvious, to me the the leaves and traps look very similar. Whaddya think?

    I don't really know many pygmy names but they appear to be pretty close...

    I perused the site - twice - but they only mentioned D. pygmaea and didn't discuss Petiolaris Complex plants at all. Maybe I missed something?

    Hey Jim,

    My phylogeny work suggests that petiolaris-complex & pygmies are sister groups. They sure do look like they're related, don't you agree??

    They certainly do! And when someone posts a picture of just the plant, without size perspective, a Petiolaris plant has that leaf and cup shape of a pigmy. I wondew why the pigmy dews produce gemmae whereas the Petiolaris do not.

    Jim,
    Yup. About 1/3rd of the way down the page, there are 2 diagrams on the left side. Click on the lower one to get a larger version ... If it's not large enough to read, you can 'stretch' the frame & make it larger (at least in my browser).
    All the best,
    Ron

    'Cause they gots no reason to. They clearly are different, and evolved differently.
