Equisetopsida is the name of a class of plants that traditionally contains the single genus Equisetum (horsestails). However, in 2009, in an article titled "A phylogenetic classification of the land plants to accompany APG III," Mark W. Chase and James L. Reveal proposed a much broader sense for the Equisetopsida class name. In their system, Equisetopsida includes all land plants (embryophytes). Their rationale was that "If the major clades of green algae are recognized as classes, then all land plants, the embryophytes, should be included in a single class..."
The class Equisetopsida sensu Chase & Reveal, 2009, contains the following subclasses. Traditional divisions and classes, along with common names are shown in parentheses.
The following diagram shows a likely phylogenic relationship between the Equisetopsida subclasses.
