reed

Definitions:

The term "reed" refers to a plant with a long stalk that grows in the water, usually along the edge of a river or stream.

The reeds in the Nile River where Moses was hidden as a baby were also called "bulrushes." They were tall, hollow stalks growing in dense clumps in the river water.
These fibrous plants were used in ancient Egypt for making paper, baskets, and boats.
The stalk of the reed plant is flexible and is easily bent over by the wind.
