The floating fern (Ceratopterispterioides (Hook.) Hieron)

Alias: rough stem water fern, floating leaf fern. Water fern fern. An annual floating herb. The plant height is 28-55cm, its nutrition leaves are single leaves, the leaves are broad triangles, and the length is 18-25cm. It is a feathery deep crack with 3-7 lobes and broad ovate triangles. The petiole is stout and the sponge cells in the stem contain air, causing the entire plant to float on the water. The leaf axis of the spore leaves expands into a cylindrical shape; the leaves show multiple feathery cracks, and the last lobe is narrowly tapering and apex acuminate.

Produced in the provinces south of the Yangtze River in China; wild fern ferns often float in lakes and ponds. The cultivated plants grow well at a temperature of 22-30°C; they have a strong adaptability to the water environment.

It is advisable to choose a pond with a calm surface facing the sun.

In the garden landscape, dotted with several clusters of floating ferns, the landscape effect is good; in the family half-view aquarium, it is often used for landscaping, and its ornamental effect is also good.

The fertile leaves are usually longer than the sterile leaves, with two pinnate divisions; the pinnacles split into linear lobes; the last lobes are 1.5-4 cm long, about 2 mm wide, and the edges are reeled, thin and transparent.

The sporangia grow along both sides of the longitudinal veins of the fertile leaf segments and is covered by the edges of the lobes.
