The Geranium Ready to Give Pollen 



This direct color photograph print shows the stamens of 



a geranium, greatly enlarged, as then cluster around the pistil at 



the time their pollen is ready for the entering insect. Each of the five 



stamens bears an anther, or pollen sac, which, as will be seen, 



bursts open and turns inside out when the pollen is ready.
