Wildflowers       Bladderworts

Flowers. Note the prominent horn hanging straight down. In Common Bladderwort (Urticularia vulgaris), this horn sticks out toward the front of the flower.

Another view of this unusual flower.

A super closeup view.

There is usually one flower per stalk (plant), but often there are two, and sometimes even three.

This is about all that is visible of this plant. The stalk rises straight up from the mud. There are no leaves or roots visible.

This bladderwort does not float like the Common Bladderwort (Urticularia vulgaris) and Flat-leaved Bladderwort (Urticularia intermedia).
