Предлагаемая классификация сосудистых споровых представляет современный подход к выделению таксонов разного ранга, в основу которого в качестве основного критерия взята монофилия. Анализируются противоречивость сведений о птеридофлоре по данным флористических сводок по Кавказу и региону. Конспект споровых сосудистых растений Западного Кавказа представлен 2 монофилетическими классами, 7 монофилетическими порядками, 11 семействами, 31 родом и 74 видами. Приводятся ключи для определения семейств, подсемейств, родов и видов. Рассматривается проблема Pteridium aquilinum и Pteridium tauricum. Приводятся новые таксоны: Pteridium pinetorum C. N. Page et Mill, Pteridium aquilinum subsp. brevipes, Dryopteris caucasica, Dryopteris pseudorigida (Christ.) A. Askerov, Dryopteris remota (A. Br. ex Döll) Druce.</p></abstract><trans-abstract xml:lang="en"><p>For the first time, an attempt was made to make a taxonomic classification of vascular spore Lycophytes and Pteridophytes of the Western Caucasus based on published phylogenetic data. The proposed classification of vascular spores represents a modern approach to the allocation of taxa of different ranks, which is based on monophilia as the main criterion. The article analyzes the inconsistency of information about pteridoflora according to the data of floral reports for the Caucasus and the region. The summary of spore vascular plants of the Western Caucasus is represented by 2   monophyletic classes, 7 monophyletic orders, 11 families, 31 genera and 74 species. Keys for defining families, subfamilies, genera, and species are provided. The problem is considered Pteridium aquilinum and Pteridium tauricum. New taxa are given: Pteridium pinetorum C. N. Page et Mill, Pteridium aquilinum subsp. brevipes, Dryopteris caucasica, Dryopteris pseudorigida (Christ.) A. Askerov, Dryopteris remota (A.
