There is something especially fascinating about plants that grow in the water. They are generally odd and striking. They are perhaps just out of reach, and if you cannot hire a barefooted boy, you must get a row-boat in order to secure the treasures. They look so cool and clean, and rest so quietly upon the lake's placid surface! The bright colors of the flowers mingle harmoniously with their large, undivided, or else finely cut, seaweedlike leaves - for our aquatic foliage is apt to run to one of these extremes.

We have not many aquatics. Sometimes swamp plants become aquatic, and those which generally live in water may become stranded and rooted on muddy banks.

Tape Grass. Eel Grass (Valisneria spiralis). Family, Frog's-bit. The ribbon-like leaves grow 6 feet long, wholly submerged or floating at the ends. Staminate flowers break off and float on surface. Pistillate flowers grow on long stems, until they reach the surface. After pollination they coil spirally, contracting, and ripen their fruit under water. Common and well known along our shores.
