G. F. Scott Elliot
- any aquatic plant of the genus Ceratophyllum, forming submerged branching masses in ponds and slow-flowing streams: family Ceratophyllaceae
- any of a group of bryophytes belonging to the phylum Anthocerophyta, resembling liverworts but with hornlike sporophytes
- Any of about 100 species of small bryophyte plants belonging to the phylum Anthocerophyta. Unlike liverworts but like mosses, hornwort sporophytes have stomata. The hornwort gametophyte consists of a low thallus, out of which numerous slender, upright sporophytes tipped with sporangia grow. The sporophyte has a meristem that elongates the sporophyte with new growth, a feature that distinguishes the plant from the other bryophytes. The name of the hornworts was suggested by the hornlike appearance of the sporophytes. See more at bryophyte.
