Our mystery plant for May, 2020 is a small alternate- leaved, easily overlooked aquatic plant.  This plant has separate male and female flowers which are located in the leaf axils.  The stamens and pistils are clearly visible in some of the photos.  These plants are small and easily over looked and can best be found when ponds dry down in the summer. In fact there are a number of rare plant species that can be found in such dried-down habitats as this.

It’s. . .
