Taxonomy and naming The genus Psilotum was first formally described in 1801 by Olof Swartz and the description was published in Journal für die Botanik (Schrader). The name of the genus is from the Ancient Greek word psilos meaning "bare", "smooth" or "bald" referring to the lack of the usual plant organs, and the seeming lack of leaves.
