Lovely flower.
The bat pollinated Passiflora have all the anthers round one side as in your photo so they dust the heads of the bats as they come in. The androgynophore (stalk the pollen anthers & stamen are on the end of) comes out of the side rather than the middle of the flower so the bats can get their tongues in. In the link below there are some great pictures of bats pollinating P. mucronata and other Passiflora in the wild.

Here is a link that might be useful: Passiflora bats.

Thanks for the link!
We have bats here, I see them dipping and diving in the air at dusk. Maybe I'll get enough flowers that they'll visit.

Thats a neat looking flower! I would love to see a bat pollinating it.
