My Pinguicula lutea is blooming now... and soon to follow are P. laueana and P. primuliflora and another P. lutea. If I do nothing, will these flowers self-pollinate? Are they self-fertile?
I'm not too interested in hybrids, but it would be nice to have some pure species seed.

I tried pollinating the first P. lutea flower without success. The second flower is now open, and so are P. laueana and P. primuliflora. I'll try again and see if I can get lucky.

Yah I don't think this ping pollinating is going so well for me. I've tried 4 flowers now and I don't know. It's not as easy as it is with irises... which I'm so much more accustomed to working with. I can barely get any pollen, it seems. Well, we'll see if any seed pods form.

The pollen is produces over a period of several days, like about three to four. You can lift the flap (behind and above are the anthers) and see if there is any pollen. Member of the primuliflora-group, all the plants you have, have deep tubes, so it is much easier to check the pollen production and collect it by removing the bottom half of the flower. You'll have much better access to the pollen flap.
I don't know, I think there are only few Pinguicula species which can auto self pollinate, the flowers all nearly all are shaped so as to prevent auto self pollination and to encourage out crossing. However, they are self fertile so you can make seed from self pollinating most species, and this includes all species native to North America.
P. laueana is a Mexican butterwort, not sure if it can be selfed... However, it should be easy to see and collect the pollen as the pollen flap is right in the front and center of the flower.
