The genus 'Ophioglossum' has the highest chromosome counts of any known plant.

It is closely related to, and sometimes treated as a subgenus of, the genus Ophioglossum.

The name Ophioglossum comes from the Greek, and means "snake-tongue".

Ophioglossum has the highest chromosome count of any known living organism, with 1,260 chromosomes.

Ophioglossum, a genus in the family Ophioglossaceae.

Small adder's-tongue (Ophioglossum azoricum) has not been seen since at least the mid-1980s.

It is a fern in the Ophioglossaceae family, and many people still classify it as an Ophioglossum.

This heath is unique because all three Ophioglossum species found in the British Isles have been recorded within this small area.

The record holder is Ophioglossum reticulatum, with about 630 pairs of chromosomes (1260 chromosomes per cell).

Ophioglossum engelmannii (N)

Ophioglossum azoricum (small adder's-tongue) is a small fern of the family Ophioglossaceae.

Occurrence of Ophioglossum fibrosum Schum.

Ophioglossum pusillum is a species of fernlike plant in the family Ophioglossaceae known by the common name northern adder's tongue.

The large rhizome mass of Drynaria can also serve as growing substrates for other plants like the ribbon fern (Ophioglossum pendulum).

Adderstongue fern (Ophioglossum vulgatum)

It is the only site in Great Britain and Ireland for the small fern, least adder's-tongue (Ophioglossum lusitanicum).

The high record would be somewhere amongst the ferns, with the Adder's Tongue Fern Ophioglossum ahead with an average of 1262 chromosomes.

Other plants include adder's-tongue (Ophioglossum vulgatum) and small adder's-tongue(O. azoricum).

Members of Ophioglossaceae are usually terrestrial (excepting a few epiphytic species of Ophioglossum) and occur in both temperate and tropical areas.

This taxon is sometimes treated as a subspecies of Ophioglossum vulgatum, as O. vulgatum ssp.

It has a fused sporangial structure similar to Ophioglossum, but a vegetative structure, with palmately-radiating pinnae, reminiscent of Helminthostachys.

This species is thought to be derived from a hybrid between Ophioglossum vulgatum and Ophioglossum lusitanicum.

Ophioglossum (adder's-tongue) is a genus of about 25-30 species of Ophioglossales in the family Ophioglossaceae, with a cosmopolitan but primarily tropical and subtropical distribution.

Ophioglossum vulgatum, commonly known as the Southern adderstongue, is a species of the plant genus Ophioglossum.

The meadows are habitat for many wildflowers including pepper saxifrage, sweet vernal-grass, heath spotted orchid, adder's-tongue fern (Ophioglossum), bugle, ox-eye daisy and common knapweed.

The flower color is distinctive among all western North American Erythronium species.

After other chemists rejected his discovery of erythronium he retracted his claim.

Erythronium, commonly called Trout Lily, have white stolons growing from the bulb.

A number of bulbous species produce stolons, such as Erythronium propullans.

In contrast with its closest relative, Erythronium dens-canis, the anthers are yellow.

He named it erythronium.

Friedrich Wöhler later confirmed that vanadium and erythronium were the same substance.

Bulbs such as scilla or erythronium are ideal for naturalising in such an environment.

Dwarf trout lily (Erythronium propullans) is listed as endangered.

It is native to Europe, where it is the only naturally occurring species of Erythronium.

Erythronium dens-canis, the common dog's tooth violet, has attractively blotched and marbled leaves.

The plants are believed to be a mutation or sport of the white trout lily (Erythronium albidum) and evolved following the most recent ice age.

Erythronium albidum (N)

Erythronium umbilicatum (Dimpled trout lily) is a species of flowering plant in the lily family.

He called the mineral "brown lead" and asserted that it contained a new element, which he first named pancromium and later, erythronium.

The Erythronium multiscapoideum lily plant grows from a bulb two to five centimeters long, sometimes with associated bulblets.

Erythronium americanum (yellow dogtooth violet)

A. Your friend's lilies are probably Erythronium americanum, which has leaf patterns like a trout's markings and springs into view when trout season opens.
