Type specimens of names of species authored by Pourret conserved in the Salvador herbarium (BC)

Abstract The Salvador herbarium, conserved in the Botanical Institute of Barcelona, is one of the oldest in Spain, with 4,025 sheets gathered between the end of the 17th century and the middle of the 18th. We designate four lectotypes (for Acer hispanicum, Achillea chamaemelifolia, Rumex pyrenaicus and Vicia pyrenaica ) and note the existence of seven isotypes of species names authored by Pourret that are conserved in BC‐Salvador and in MAF‐Pourret herbaria. The taxa involved were described under the pre‐Linnaean system by Joan Salvador, and then Pourret used duplicates of some of them to publish new taxa in his "Chloris narbonensis".
