Botanic Garden of the Jagiellonian University hosts an old collection of currants and gooseberries. Detailed documentation from the time of Edward Janczewski (1846-1918), who expanded the collection for his work on taxonomy of the genus, is preserved at J. Dyakowska Botanical Museum. It includes list of specimens, maps and microscope slides. Herbarium sheets preserved at the Jagiellonian University Herbarium (KRA) provided further information on the origin of specimens. Janczewski received plants, seeds and herbarium sheets from individual researchers, botanical gardens and herbaria, including Arnold Arboretum, Berkeley, Darmstadt, Edinburgh, Kew, Paris, Petersburg and Tomsk. The specimens were collected by many scientists and explorers, including Nikolaj Michailowicz Przewalski (1839-1888), Joseph Dalton Hooker (1817-1911) and missionaries in China and Japan, including Armand David (1826-1900). Janczewski’s collection of living plants included species from Asia, Europe and North and South America and at its best consisted of 251 specimens representing 101 species and varieties. Some plants were later planted also in Kórnik Arboretum, but this collection did not survive. Only a small part of living collection in Botanic Garden of the Jagiellonian University survived. Fortunately, it includes specimen of Ribes warszewiczii grown in 1862 by Józef Warszewicz from seeds obtained from Siberia. It probably served as a type material for this taxon description. The paper includes a full list of specimens and maps from both the original and preserved collection.
