  1. Great job! Did you notice anything special about the pollen? If you get around to it, check it out. There are special viscin threads that hold together the pollen grains. When a bee comes to collect the pollen, they cannot collect individual grains, they are transferred in packages held together by these viscin threads. Kind of unique to the Onagraceae.
