An abortive flower[2] is a flower that has a stamen but an under developed, or no pistil.[3] It falls without producing fruit or seeds, due to its inability to fructify. Flowers require both male and female organs to reproduce, and the pistils and ovary serve as female organs, while the stamens are considered male organs. Illustrative examples include Urginea nagarjunae and Trichilogaster acaciaelongifoliae.
Studies have shown that hermaphrodites or bisexual flowers have higher rates of fruit abortions than unisexual flowers.[4][5]
