Equisetaceae

Index Equisetaceae

Equisetaceae, sometimes called the horsetail family, is the only extant family of the order Equisetales, with one surviving genus, Equisetum, which comprises about twenty species. [1]

16 relations: Devonian, Equisetales, Equisetum, Equisetum arvense, Fossil, Genus, Holocene, Jurassic, Mesozoic, Myr, Neontology, Paraphyly, Pseudobornia, Secondary growth, Species, Wastebasket taxon.

Devonian

The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya.

Equisetales

Equisetales is an order of Equisetopsida with only one living family, the Equisetaceae, containing the genus Equisetum (horsetails).

Equisetum

Equisetum (horsetail, snake grass, puzzlegrass) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds.

Equisetum arvense

Equisetum arvense, the field horsetail or common horsetail, is an herbaceous perennial plant in the Equisetopsida (the horsetails), native throughout the arctic and temperate regions of the northern hemisphere.

Fossil

A fossil (from Classical Latin fossilis; literally, "obtained by digging") is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Genus

A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.

Holocene

The Holocene is the current geological epoch.

Jurassic

The Jurassic (from Jura Mountains) was a geologic period and system that spanned 56 million years from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period Mya.

Mesozoic

The Mesozoic Era is an interval of geological time from about.

Myr

The abbreviation myr, "million years", is a unit of a quantity of (i.e.) years, or 31.6 teraseconds.

Neontology

Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, recent) organisms.

Paraphyly

In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups.

Pseudobornia

Pseudobornia is a genus of plants known only from fossils found from the Upper Devonian.

New!!: Equisetaceae and Pseudobornia · See more »

Secondary growth

In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.

Species

In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.

New!!: Equisetaceae and Species · See more »

Wastebasket taxon

Wastebasket taxon (also called a wastebin taxon, dustbin taxon or catch-all taxon) is a term used by some taxonomists to refer to a taxon that has the sole purpose of classifying organisms that do not fit anywhere else.
