Equisetaceae Michx. ex DC.
The plant family Equisetaceae was named and described by André Michaux and Augustin Pyramus de Candolle in Essai sur les Propriétés Médicales des Plantes in 1804.
The genus Equisetum is the only member of this family, which is commonly known as the horsetail family. The 2013 version of The Plant List (no longer maintained) also named the genera Allostelites and Hippochaete. There were one species of each and they have been moved to the genus Equisetum.
Equisetum are among the oldest plants on the planet as shown in fossil records dating back about 375 million years.
The only species I am familiar with is Equisetum hyemale (Horsetail). Click on the name to go to its own page…
