    Here is a photo showing this hairy appendage (or beard) and the stigma above and behind it --> the pollen, anthers and stamen are behind/beneath this stigma flap.


    If you tear off the corolla lobe containing the beard, the spur, attached behind the beard will also be torn away. This will also expose everything necessary to easily complete the mission of pollinating or self-pollinating the flower.
    Very good advice by Joseph Clemens! Thanks!!!

    Took some photos today while pollinating a P. Sumidero 1 flower so thought id post them.

    Flower before being torn apart:


    After the bottom 3 petals were torn off to expose the stigma flap (the top dark blue/purple part is where you put the pollen, and the pollen is located below this flap):


    Stigma flap lifted to reveal the pollen on the antlers (pollen has already been removed):


    Pollen deposited on the outside of the stigma flap (compare to photo 1 to see the slight color difference):

    Here is a couple photos one week after pollinating. As you can see the seed pod is already starting to grow and become visible.

    And about 4 weeks after pollinating, pod will open any day now and when it does you have to be quick before they fall out

    Thought I would update this for a final time. Flower was pollinated Oct. 31, 2011, seed harvested Dec. 1, 2011.

    P. Sumidero 1 seeds from the pod pictured in my previous posts (please ignore the terrible cellphone picture):

    Maybe crossing with crosses doesn't work?

    P. laueana flower

    Up until recently, i hadn't really tried to pollinate very many of my Pinguicula flowers, but lately i've had success with pollinating some P. lilacina flowers and germinating the seed from those attempts.

    I attributed that success to the rather roomy interior of the P. liacina flowers and also the relative closeness of the stigma flap to the flower's opening, making for easier working/pollinating conditions

    This P. laueana flower is currently in the final stages of being fully opened, and i had a closer look at it today to try and determine how difficult this flower might be to pollinate.



    I was surprised to see the stigma flap was right flush at the throat opening of the flower and that pollen was clearly visible behind the flap, to the left, once i had a closer look.



    Having everything up front and centre does make for a much easier pollination atempt.
