The underwater stem and leaves of Batrachium circinatum are topped by half inch, five-petaled white flowers that float on the water's surface.  Plants are often numerous and quite evident even though the flowers are so small.

"Batrachium" is Greek for "frog", apparently alluding to the habitat and "circinatum" is Latin for "ring" or "circle" and refers to the curving of the leaves.
