  A Fondness For Ferns - Minnesota Conservation Volunteer: Minnesota DNR
Ferns and their allies differ from mosses in that they have a vascular system-tubes that carry water and nutrients from one part of the plant to another.
In contrast, fern allies tend to have small leaves, and their sporecases are single on some leaves or grouped in cones at the top of the plant.
To reproduce, ferns and their allies shed spores, which land on the ground and develop into tiny plant forms, which are all but invisible to us.

  Fern ally
Fern ally is a term for a diverse group of vascular plants that are neither flowering plants nor ferns and which reproduce by shedding spore to initiate an alternation of generations.
There are four main groups of plants considered to be "fern allies." In various classification schemes, these may be grouped as classes or divisions within the plant kingdom.
The ophioglossoids (Ophioglossopsida) were once thought to be ferns, but are now known to be distinct due to genetic studies.

 Fern ally - Wikipedia, the free encyclopedia
Note that in either scheme, the basic subdivision of the fern allies is preserved, with the exception that the Ophioglossophyta (Ophioglossopsida), once thought to be true ferns, are now generally regarded by many to be a distinct group of fern allies.
fern allies": the clubmosses, spikemosses, and quillworts in the Lycopodiophyta, the whisk ferns in Psilotaceae, and the horsetails in the Equisetaceae.
In fact, the whisk ferns and Ophioglossoids are demonstrably a monophyletic clade, and the horsetails and Marattiaceae are arguably another clade.

Pteridopsida A fern, or pteridophyte, is any one of a group of some twenty thousand species of plants classified in the Division Pteridophyta, formerly known as Filicophyta.
A fern is defined as a vascular plant that does not produce seeds, but reproduces by spores to initiate an alternation of generations.
Ferns have traditionally been grouped in the Class Filices, but modern classifications assign them their own division in the plant kingdom, called Pteridophyta.

 Devonian Times - More about Ferns
Modern ferns are familiar spore-producing plants common in a wide range of tropical to temperate environments.
The most widely accepted previous schemes placed three groups of extant ferns (Marattiales, Ophioglossales and leptosporangiate ferns) within the "true ferns" while two other groups, sphenophytes (horsetails) and Psilotales (whisk ferns) were regarded as more distantly related "fern allies" that may or may not be "true ferns".
Whisk ferns (Psilotales) have no roots, greatly reduced leaves and spore producing organs that are borne on short lateral branches; all other ferns produce spores on their leaves.
