"Sparganium natans" is a species of bur-reed known by the common name small bur-reed. It is a water plant native to high elevation lakes and marshes of Canada and the northern United States. It is usually found submersed in shallow, calm water. This bur-reed has thin, flexible, grasslike leaves which float in the water. Plants that spend more time out of water at the waterline are tougher and have shorter leaves. The plant bears two inflorescences, the staminate type being a rounded white filamentous ball and the pistillate type a sphere of thick, green, pointy peduncles. The fruits are small green or brown achenes.
