Prodromus Systematis Naturalis Regni Vegetabilis (1824–1873),[1] also known by its standard botanical abbreviation Prodr.
De Candolle intended it as a summary of all known seed plants, encompassing taxonomy, ecology, evolution and biogeography.
His son, Alphonse de Candolle, then took up the work, editing a further ten volumes, with contributions from a range of authors.
Note that this system was published well before there were internationally accepted rules for botanical nomenclature.
Neither of these phenomena is a problem from a nomenclatural perspective, the present day ICN provides for this.
