Thanks, Julie, that is interesting regarding the number of stamen that must be present in order to not be downgraded in judging. I could not recall, offhand, what 'Four Star' did in my garden; I do vaguely recall that some of the early diploid polymerous daylilies could be inconsistent in the number of stamen, even when displaying 8 tepals. (The only dip polymerous daylilies I still have in my garden are 'Give Me Eight' and a few seedlings, and I have not been paying all that much attention to the number of their stamen.)
Looking at the images in the ATP database, it appears that 'Four Star' was one of the inconsistent ones:
I am editing to say that I cannot recall with 100% certainty if 'Four Star' ever produced any true petaloid tissue. If it did so - in my garden - it must have been a fairly infrequent event. Certainly most of the blooms were 4x4, regardless of the number of stamen present.
