Do all your flowers have pistals in them? I have noticed that some of my flowers in clusters have the pistals and some flowers do not. At first I noticed this on my NZL and then examined yesterday my eldest tree which is a 16 y/o Meyer lemon and noticed differences in the flowers around the tree like my NZL. I originally believed that trees without complete flowers were just immature, but I have no explanation for my Meyer. Anybody have an explanation?
