New data to distribution of ferns in Tajikistan (Middle Asia)

subject

description

The paper presents new chorological data of eleven fern species (Ophioglossum bucharicum, Azolla filiculoides, Botrychium lunaria, Gymnocarpium robertianum, Cryptogramma stelleri, Polystichum aculeatum, Asplenium trichomanes, Asplenium viride, Asplenium ruta-muraria, Adiantum capillus-veneris and Salvinia natans) in central Pamir Alai Mts in Tajikistan. Except Azolla filiculoides all of them are native to the flora of Tajikistan. The dry and warm climate in lowlands and middle mountains as well as harsh conditions in higher elevation of Pamir are not suitable for Pteridophytes. Thus, many of fern species are rare in Tajikistan, having less than five locations. List of localities of the species in the territory of Tajikistan with distribution map of chosen species is presented.
