Ophioglossum pusillum

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

It is native to northern North America, where it is widespread in moist areas such as marshes, fens, and meadows. It is found from northern California through Alaska on the west, and from central Appalachia through the northern Great Plains and the Great Lakes regions, across the Northeastern United States and Eastern Canada.

Description

Ophioglossum pusillum is a small, inconspicuous, fleshy perennial plant growing from a caudex no more than 3 centimeters wide. It produces one leaf per year.

The leaf is divided into a thin, pale green blade-shaped part, which is sterile, and a fertile stalk lined with two rows of sporangia.

Ophioglossaceae, the adder's-tongue family, is a small family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, it is the only family in the order Ophioglossales, which together with the Psilotales is placed in the subclass Ophioglossidae. The Ophioglossidae are one of the groups traditionally known as eusporangiate ferns. Members of the family differ from other ferns in a number of ways. Many have only a single fleshy leaf at a time. Their gametophytes are subterranean and rely on fungi for energy.

<i>Hordeum pusillum</i> Species of grass

Hordeum pusillum, also known as little barley, is an annual grass native to most of the United States and southwestern Canada. It arrived via multiple long-distance dispersals of a southern South American species of Hordeum about one million years ago. Its closest relatives are therefore not the other North American taxa like meadow barley or foxtail barley, but rather Hordeum species of the pampas of central Argentina and Uruguay. It is less closely related to the Old World domesticated barley, from which it diverged about 12 million years ago. It is diploid.
