Specifically, he focuses on heterostyly, or plants that bear flowers with differently sized sex organs - a highly-evolved trait developed to encourage crossbreeding. The Different Forms of Flowers on Plants of the Same Species is a continuation of Darwin's exploration of his that cross-pollinated plants would produce biologically superior offspring to those of self-pollinated plants, which he theorized in On the Origin of Species (1859) and demonstrated in The Effects of Cross and Self Fertilization in the Vegetable Kingdom (1876).
