The collections from the Royal Spanish Expeditions to Latin America conserved in the Institut Botànic de Barcelona, comprising 695 specimens, illustrate the changing fortunes in the study of the flora of tropical America by Spanish botanists and their herbarium material. We present data on the collectors, the collection localities and the expeditions, and as electronic supplement, a list of all specimens with collecting data and the determinations on the sheets.
