Equisetaceae Family:

Equisetum hyemale (Horsetail) on 9-24-21, #835-16.

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. There are 18 species in that genus (as of 12-20-22 when this page was last updated).

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…
