Dryopteris

 

a genus of ferns of the family Aspidiaceae. There are about 150 species, distributed in the temperate zone of Eurasia and North America and, to a lesser extent, in the tropical regions of Asia, Africa, and South America. The USSR has about 15 species. Especially widely distributed is the male fern (D. filix-mas). D. carthusiana (formerly D. spinulosa) is found in damp, mossy forests of the European USSR, the Caucasus, and Siberia. Both species are used medicinally as anthelmintics. D. fragrans grows on cliffs and slopes of the northern European USSR, in Siberia, and in the Far East; D. cristata grows in humid regions and swamps in the European USSR and Western Siberia.
