The *Botanisches Centralblatt* was accepted as the "Referirendes Organ der Association" (vols. 89-142, 1902-1919). Lotsy also published *Progressus rei botanicae* (1-5, 1907-1917, IDC 7342) for the Association as well as a volume *Résultats scientifiques du Congrès international de Botanique*, Vienne, 1905. The "Association" and the "International Committee for Botanical Nomenclature" (which functioned well from 1905 onward) were forerunners of the Botany Section of the later (1923) *International Union of Biological Sciences*, and more specifically of the present *International Association of Plant Taxonomy*. Lotsy founded and edited *Genetica* (vol. 1-3, 1919-1921, co-editor 4-12) as well as *Bibliographia genetica* (1924) and *Resumptio genetica*. #### Eponymy (serial) *Lotsya*.
