The article provides information about the general classification of the Ferns department. It became known that the plants of the Ferns branch were studied and scientifically classified by Theophrastus from the beginning of the 16th century. Later Andrea Cesalpino, Carl Linnaeus, J.E. Smith, Bernhardin and others were developed taking into account morphological and anatomical features. In his five-volume Species of Filicum, Hooker described 2400 fern species in 63 genera and improved their taxonomy. In 2006, research botanists Alan R. Smith and Petra Koral at the University of Berkeley proposed a new classification based on molecular studies in addition to morphological data. Based on this division, ferns are divided into 4 classes: Psilotopsida; Equipetopside; Marathiopsida; At Polypodiopsis.
