What I believe that you are seeing is normal aging of the flower. The first 24-30 hours that the flowers are open, the anthers have that long "shield" on them, which will fall away, exposing the pollen filled anther underneath. Also the three-lobed stigma is still closed when the flower first opens. To me, the top two photos are of a newly opened flower with the shields on the anthers and the closed stigma. I think one or two of the shields has already fallen off. The two lower photos are of a flower which could be a day older: the shields on the anthers are gone and the 3 lobes of the stigma have spread apart, the stigma elongates, the anthers and stigma curve upward. Also, the lower flower looks older since the edges have ruffled and it just looks "showier". Occasionally, the shields don't fall off and I gently remove them. Maybe that's what you are seeing. However, that is more often seen in doubles that have strange reproductive parts. Without seeing the actual plant, this is all speculation on my part. Anyone else have any ideas?
