Yes! Sorry, wrong terminology, I did mean the style.
When you say an aging flower, do you mean the bloom, or the actual fan itself? The curly style was a one-time thing (so far) on my Jungle Beauty plant I just purchased in the last few weeks. It was the first issue with a style that I've had on her (she's probably bloomed 8-10 times since I've had her). I wish I had taken a picture, but I was in a hurry.
That's interesting about the stigmatic fluid time frame and the anthers. Good to know!
