The plant body of a hornwort is a haploid gametophyte stage.

Close to the shore, long tresses of hornwort held fast, winnowed by a gentle current.

In either case, the protonema is a transitory stage in the life of a hornwort.

The spineless hornwort usually does not have any roots with stems that are freely branching (0.3-4.0 m long).

During the 1990s, aquatic plants, mostly Rigid Hornwort, have spread and now covers the lake bed.

Such colonies of bacteria growing inside the thallus give the hornwort a distinctive blue-green color.

The thallus cells often contain more than one chloroplast, as opposed to other hornwort genera.

Sphaerosporoceros is a genus in the hornwort family Anthocerotaceae.

The species is placed in a separate family, order, and class for being "genetically and morphologically distinct from all other hornwort lineages."

Water plants such as reed mace, reed, bulrush, buttercup and hornwort are met in the lake.

(Prickly Hornwort)

Cladistic analysis of genetic data supports a position at the very base of the hornwort clade.

Leiosporoceros dussii is the only species in the hornwort genus Leiosporoceros.

Ceratophyllum submersum (soft hornwort) is a species of Ceratophyllum.

Phymatoceros is the only genus in the hornwort family Phymatocerotaceae and order Phymatocerotales.

Hornwort (Ceratophyllum demersum)

Tropical hornwort (Ceratophyllum submersum)

The name Hornwort also refers to aquatic plants of the genus Ceratophyllum, in the family Ceratophyllaceae.

There are a few localised examples of the Rigid Hornwort (Ceratophyllum demersum).

It seems to be associated with floating vegetation such as Hornwort and Water Milfoil (Myriophyllum).

Phaeoceros laevis is a species of hornwort of the genus Phaeoceros.

They may occur alongside scarce species including lesser centaury, curved hard-grass and sea pearlwort, with soft hornwort in the dykes.

Ceratophyllum demersum recorded increase in the lake area.

Of these, 'Ceratophyllum demersum' is widespread, with a global distribution; the others all have more restricted ranges.

Plants with the two basal nut spines very short are sometimes distinguished as Ceratophyllum demersum var.

Its vegetation is characterized by Ceratophyllum demersum and Nymphaea lotus.

Ceratophyllum demersum (N)

Asch., and those with no basal spines sometimes distinguished as Ceratophyllum demersum var.

Ceratophyllum demersum grows in lakes, ponds, and quiet streams with summer water temperatures of 15-30 C and a rich nutrient status.

Coontail (Ceratophyllum demersum) was present at one time, but the sandy bottom made it hard for it to survive.

The main aquatic plants in the lake are Najas graminea and Ceratophyllum demersum.

There are a few localised examples of the Rigid Hornwort (Ceratophyllum demersum).

Hornwort (Ceratophyllum demersum) The Hornwort has a worldwide distribution, so it's suitable for most set-ups.

Still in deeper water an association of manel Nymphaea stellata and the submerged aquatic plant Ceratophyllum demersum present.

Ceratophyllum demersum L. (Rigid Hornwort or Common Hornwort)

Ceratophyllum demersum (hornwort, rigid hornwort, coontail, or coon's tail) is a species of Ceratophyllum.

Nesting sites at LaRue Pine Hills were situated near Ceratophyllum demersum (coon tail) over substrate that contained fibrous root wads.

The prolific growth of Ceratophyllum demersum in the eutrophic zones has been reported, with Myriophyllum spicatum and Potemogetton lucens cited as dominant species.

There's no old-fashioned pond weed for sale in the aquatic boutiques of Long Island - it has gone up-market and acquired names like Ceratophyllum demersum and Elodea canadensis.

The larvae feed on Nymphaea alba, Potamogeton, Callitriche, Ceratophyllum demersum, Elodea canadensis, Nuphar lutea and Stratiotes.

Dominating aquatic macrophytes: Potamogeton welwitschii + Ceratophyllum demersum (submerged); Eliocharis dulcis, Oryza barthii, Vossia cuspidata, etc. (Ojda 1994)
