  World of Equisetum
The Horsetails are plants of a single living genus, Equisetum, and of the single family Equisetaceae of the single order Equisetales and the single classis Sphenopsida.
These curious plants are the relicts of an ancient family known through fossils from as early as 325 million years ago, the geological period (Upper Carboniferous) when the remains of plants became the vast coal deposits that we use today.
The species of Equisetum are found growing in wet places, such as standing water of shallow ponds or ditches, marshy areas, wet meadows, and moist woods.

 Mexico Desconocido: plants in extinction Equisetum   (Site not responding. Last check: )
It was during this period that species and forms of equisetum reached their greatest degree of diversity, ranging from small aquatic herbs (similar to those that exist today) to some amazing samples between 15 and 20 meters in height.
The magnificent equisetum forests (and their close relatives, the calamites –; a similar looking plant but much larger) started disappearing about 280 million years ago, during the Permian era, and by the end of the Tertiary period, some two million years ago, only a few herbaceous species were left.
Equisetum plants can be found in the herb section of markets in some remote villages and even in some of the bigger cities, where modern methods mix with ancestral traditions.

 National Collection of Equisetum: A Brief Introduction to Equisetum
The genus Equisetum ('Horsetails') are the survivors of a major division of the plant world, quite distinct from other groups such as flowering plants, conifers and ferns.
Equisetum is the sole surviving genus of the class Sphenopsida, which in the Carboniferous period included tree-like forms, growing to over 30m, such as the Calamites whose fossil remains are a major contributor to the coal measures.
These plants were similar in form to the modern Equisetum, differing mainly in their size, the degree of branching and the existence of secondary ('woody') thickening of the stems.

Note : Equisetum arvense should not be confused with members of the genus Laminaria, kelp, or brown alga, for which "horsetail" has been used as a synonym.
The name Equisetum is derived from equus, "horse" and seta, "bristle." Preliminary human and laboratory research suggests that horsetail may increase the amount of urine produced by the body.
Standardization may be difficult, as approximately 25 species of Equisetum exist, and it is often difficult to differentiate between species.
