The plant systematics has been dominated by the Euanthium Theory for over hundred years. Despite all progress made, several important problems defy solutions and block further progress of botany, and one sometimes even sees conflicts among different branches and schools in botany. From the history of botany in the past centuries, it is realized that the stasis in the current plant systematics is actually a result of a blind reverence to authority and the self-restriction within the dominating theories. Any progress in the plant systematics would not be possible without dropping these burdens. A new testable hypothesis on the making of flowers is advanced in this paper.
