Why are there staminate flowers and not just perfect (hermaphroditic) flowers?

The tree has to moderate the number of pistils it is able to develop with the nutrients available to it; 2) In order to pollinate the pistil, the tree is dependent on a high volume of stamens – stamens don’t have the same nutrient requirements as the pistils, so the tree exercises her “nutrient economizing” by terminating pistils (ovules) as needed.
