A record and discussion of the Cunene-Zambezi Expedition that took place in Angola from 1899 to 1900 is provided. Although the main aim of the expedition was to evaluate the economic potential of southern Angola, it also resulted in significant botanical collections made by Hugo Baum (1867-1950), many of which serve as holotypes of names of plants from the region, and beyond. The itinerary is supplemented by a map illustrating the route followed by the expedition, and locality names are clarified and updated. A full list of the type specimens of flowering plants is provided, with their nomenclature updated and an indication of where known duplicates are housed.
