  NationMaster - Encyclopedia: Whisk fern
The whisk ferns, traditionally thought not to be true ferns, are odd, "primitive" vascular plants that reproduce solely by spores, without seeds.
Ferns are dispersed by air-borne spores which have a thick, protective wall that surrounds a living cell.
Whisk fern spores are borne in infrequently seen yellow lobes which form the base of the scales.

Fern ally is a general term covering a somewhat diverse group of vascular plants that are not flowering plants and not true ferns.
Several groups of plants were considered "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 clade, and the horsetails and Marattiaceae are arguably another clade.

Technically, the whisk fern plant is said to have no leaves, but instead possesses minute enations along the angular stem axis and in association with the 3-lobed spore-producing structure, the synangium.
Whisk Ferns form large clumps in crooks and nannies of trees and are occasionally terrestrial in moist hammocks and well-mulched flower beds
Whisk ferns are often described as "Living Fossils?" because they are very similar in many aspects to the earliest tracheophytes of the Silurian-Devonian Periods, e.g., Cooksonia, Agalophyton.

Psilotum (whisk fern) is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris).
They had traditionally been thought not to be true ferns, but rather, odd "primitive" vascular plants similar to the fossil rhyniophytes and psilophytes.
In addition, they lack true leaves and roots (like the Bryophytes), and thus represent the simplest of vascular plants, albeit whose "simple" features are the apparent reduction from more complex evolutionary predecessor.
