Sparganium natans is a species of bur-reed known by the common names least bur-reed[1] and small bur-reed.[2] It is a water circumboreal plant inhabiting North America, Europe, West Asia and Japan. 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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
