This plant is andromonoecious which means it has both perfect and male flowers.  The perfect flowers have the potential to become fertilized and develop fruit.  The male flowers simply produce pollen and die.  The perfect flowers are sessile and their ovaries are covered with uncinate, bulbous-based prickles.  The male flowers are pedicellate and do not possess ovaries.
