Euphorbia duvalii (Euphorbiaceae)in the Iberian Peninsula

[摘要] Euphorbia duvaliiLecoq & Lamotte is an endemic species from the Catalan-Occitan territory -western Mediterranean area- and is usually found in the south of France.Euphorbia duvaliihas been cited from some localities of the Iberian Peninsula, but in later reviews all of these citations were finally identified as other species ofEuphorbiaL. One of these citations, from the Alt Empordà -Girona, Spain-, was of specific interest because not all the sources agreed on what the species was. To clarify whether or not this species is really present in the Iberian Peninsula, we examined new material from this population in order to establish whether the species is in factE. duvalii . Once the morphology of the specimens from the Serra de Bac Grillera population had been analysed, we were able to confirm that they were indeedE. duvalii . This means that this is the only area on the Iberian Peninsula where this endemic species has been identified. The population is located in a rocky meadow that contains some scrub and is surrounded by pinewoods. Because this is the one and only Iberian population, a management and conservation plan needs to be drawn up to ensure its preservation.
