Those pictures are very informative, Michelle.
Here are a few examples from other plants in the family.... often the male parts mature before the female ones.
The flower on the left is younger than the one on the right, and only the one on the right is ready to accept pollen, I think. The bottom flower is the youngest and still has not made its pollen available.
A flower with lots of pollen (male parts mature and available) and a relatively immature stigma (probably not receptive).
And in these shots you can see relatively mature female parts (increasingly glistening and increasingly spreading)
