Prodromus Systematis Naturalis Regni Vegetabilis

Prodromus Systematis Naturalis Regni Vegetabilis (1824–1873),[1] also known by its standard botanical abbreviation Prodr.

), is a 17-volume treatise on botany initiated by Augustin Pyramus de Candolle.

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.
