Taxa proposed by Pourret based on the specimens conserved in Salvador herbarium (eighteenth century)

Abstract

The Salvador herbarium (seventeenth to eighteenth century) is one of the oldest pre-Linnaean herbaria in Spain. Currently preserved in the Botanical Institute of Barcelona, it was reviewed by Pourret during the eighteenth century, who added the Linnaean name of the species to the labels and proposed many new names. Our study has allowed us to enlist all taxa proposed by Pourret (a total of 335); however, only 12 were validly published (some by other authors), and two of them are lectotypified here. We have also classified the rest of names into three categories: 35 that were included in publications by other authors but are not validly published names; 160 that were published by other authors; and 128 that we have not been able to find in any publication, and they should be considered as merely Pourret’s proposals without any validity. These results reflect the situation of plant taxonomy in the late eighteenth century; in Pourret’s time the number of published taxa was very low while taxonomical studies done by other contemporary authors were rarely available. Thus, Pourret was not able to assign already published taxa to all specimens and, therefore, he was forced to do new proposals that were mostly incorrectly published.
