    Here is link to a rough sketch to show how the Pinguicula flower is designed. If pollen is produced, it is generally released between the top of the ovary and the underside of the stigma flap (often yellow filaments produced by the corolla are mistaken for pollen). For me the easiest way to effect the capture of pollen and transfer it to the desired upper stigma surface is with a wooden toothpick, flat or round. I color the tip of the toothpick black with an indelible marker pen, then it is easiest to see anything on the toothpick tip that is lighter than "black". To capture pollen with a toothpick, I first gently remove most or all of the corolla. While gently holding the stalk below the flower I insert the toothpick under the stigma flap, between the ovary and the stigma flap. If there is any quantity of released pollen often some will be captured by the toothpick. I then gently touch the toothpick with captured pollen on its tip against the upper surface of the receiving stigma, optimally near its center. You can see my hand drawn diagram here:


    The red spot in the center of the stigma indicates the position of the style (the connection of the stigma to the ovary).

    The corolla is the "flower" part of the flower, right? (If that makes any sense...)

    How do you remove it without disturbing the anthers, etc?

    When I took pics of my Utric blooms a month or so ago, I also had my wife help me snap a pic of the internal flower parts of a U. nelumbifolia bloom (which I then forgot I had). Prior to the blooms opening, I searched all the forums for explanations & pics. While I did find a number of them, the pics were usually too small to see the details or the 'stylized' version still confused me. Combining Joseph's explanation (up above) of what to do, with his 'stylized' drawing & the following pic (showing all the parts he references) - helped me to understand how to pollinate (with some friend's hints too!).

    Here's the pic:

    I still keep trying to hand-pollinate the Mexican ping flowers... and still can't get them to produce seeds. I think I need someone to be right with me and show me. I'm not sure what I'm doing wrong. You wouldn't know it but I successfully hand-pollinated Petiolaris plants.

    Sometimes it could be the plant genetic. Many hybrids or selfing offspring might have lower fertility.
