Sorry Sven can't tell from the last two photos though they don't look like pollinias to me. In the third photo the bloom on the right shows the anther cap (white) at the tip of the column and it looks like it contains the pollinia.

I checked my Bc Maikai blooming at the moment and noticed that the column is deep inside the throat and the anther cap is very small. On pulling out the anther cap I found two very minute pollinias. I also took a peek at my Bc Richard Mueller x Sc Ann Folis and noticed that the column is very easy to see and the anther cap quite prominently displayed. I'm also puzzled as to why you couldn't find the pollinia.
