The American white water lily is an aquatic amphibious plant that displays pronounced heterophylly, the appearance of different leaf forms on a single plant. Water lilies produce leaves that either float or are held above the water’s surface. In this paper we describe the natural history of water lily leaf forms and examine some of the factors that stimulate heterophylly. Over the course of a growing season the predominant leaf form switches from surface leaves in the early season to aerial leaves in the midseason and then back to surface leaves at season’s end. Of the various factors that we investigated, changes in the light environment appear to influence heterophylly the most. Log in to add this item to your schedule
