The detailed analysis of origin of the Asplenium septentrionale (L.) Hoffm. specimens, deposited in the main collection of vascular plants’ herbarium in the SMNH NASU, has been carried out. Asplenium septentrionale (L.) Hoffm. – northern spleenwort – is a perennial fern of the genus Asplenium, the family Aspleniaceae, a Holarctic petrophilous species with a disjunctive Eurasian-North American natural range (Europe, the Caucasus, Central Asia, Western Siberia, Mongolia, Himalayas, Far East, North America). Its localities are confined to petrophilic communities, mainly on granite outcrops devoid of calcium (rock crevices, rocky slopes, landslides, boulders, shady spruce forests, etc.), and the species rises to the upper mountain belt. In Ukraine, this species occurs within the Carpathians, the Crimea, Steppe (Prydniprovska and Azov uplands, Donetsk Ridge) and Forest-Steppe (Volynska and Prydniprovska uplands) zones, Polissya (occasionally in Volynske and Zhytomyrske Polissya). Asplenium septentrionale (L.) Hoffm. has been included into the official lists of regionally rare plants in many regions of Ukraine (Dnipropetrovska, Donetska, Zhytomyrska, Zaporizka, Ivano-Frankivska, Kyivska, Kirovohradska, Luhanska, Rivnenska, Chernivetska provinces and the Autonomous Republic of the Crimea). The main collection of the Herbarium of Vascular Plants in the SMNH NASU contains 26 herbarium specimens of A. septentrionale (L.) Hoffm., all being included into the electronic database "Biodiversity of Ukraine" (http://dc.smnh.org/) and digitized. The geography of the herbarium collections of A. septentrionale (L.) Hoffm., besides the modern territory of Ukraine (Dnipropetrovska (1901), Donetska (1939, 1947, 1965, 1966), Zhytomyrska (1949), Zakarpatska (1948, 1957, 1961, 1969), Ivano-Frankivska (1967), Kirovohradska (1900), Rivnenska (1948) provinces and the Autonomous Republic of the Crimea (1900)), has been represented also by the territories of Poland (1905), Czech Republic, Slovakia, Austria, Romania (1905), Finland (1898) and the Russian Federation (North Ossetia, 1898). In descending order of the number of collected herbarium specimens with the participation of 16 collectors, the following series has been formed: Slobodian M. (3 herbarium specimens), Vainagii I. (2), Voloshchak E. (2), Hanieshyn S. (2), Lazebna A. (2), Malynovskyi K. (2), Zinger M. (2), Berko J. (1), Golde K. (1), Kotov M, Karnaukh E. (1), Markovych V. (1), Melnychuk V. (1), Rheman A. (1), Stoyko S. (1), Finn V. (1), Khrzhyzhanovskyi V., Lazebna A. (1), Shokhin V. (1). The chronology of the herbarium collections covers the period from 1898 to 1969. The earliest specimens (second half of the 19th century) were collected in Finland (V. Shokhin collection) and North Ossetia (V. Markovych collection).
