Woops! A little confusion, probably on my part.
The plant I have that is blooming is a papillio. The one that is not yet blooming is a 'Hildos'.
Anyway, when the papillio opened a couple of days ago the dorsal sepals were curled under and I thought hmmm, is it going to stay that way? I'm happy to report that today the one and only flower is fully open. Tomorrow when I have good light, I need to photograph it just for my own records. I am sure there are plenty of good, professional photos of the flower out there without mine.
