Abstract

We describe Peucedanum officinale L. subsp. album Martínez-Fort & Donat-Torressubsp. nov., in which we grouped the thermomediterranean populations scattered along the eastern part of the Iberian Peninsula. The characters that differentiate this new subspecies from other infraspecific taxa inPeucedanum officinaleare its canaliculated leaflet, the inflorescences much branched and lack of dominant terminal umbels, the umbels are few rayed, sometimes sessile and lateral, the petals are white and the fruit pedicels short, the same or shorter in length than the fruit. We provide here a full description of the new subspecies based on herbarium specimens and field measurements, as well as providing dichotomous keys to the subspecies withinP. officinale. In addition, we provide a comparison of the ITS sequences of nrDNA with the most closely related taxons.
