Ceratophyllum

 

(hornwort), a genus of plants of the family Ceratophyllaceae. The perennial underwater herbs have thin, branching stems reaching 1–1.5 m in length. The perianth of the staminate flowers is whitish and generally consists of 12 sections; the perianth of the pistillate flowers is greenish and has nine or ten sections. There are about ten species of Ceratophyllum, distributed throughout the world. The USSR has six to eight species, including C. demersum and C. submersum, which grow in stagnant and slowly moving waters. Hornworts serve as food for fish and waterfowl.
