DNA barcoding analysis of Eucalyptus camaldulensis Dehnh. (Myrtaceae)

The nomenclature of Eucalyptus camaldulensis Dehnh. (Myrtaceae) has been muchdiscussed since modern studies suggested that Dehnhardt, the author of the species, employed this name for a plant different from that indicated today with this named. A recent work carried out by a multidisciplinary approach based on examination of illustrations and herbaria specimens as well as on consultation of documents in historical archives, showed that Dehnhardt’s original description applies to the taxon currently indicated as E. camaldulensis subsp. camaldulensis. In order to support this previous conclusion, a DNA barcoding analysis was carried on both historical specimens and cultivated and wild material of E. camaldulensis. Results confirmed that there is no substantial taxonomical difference between the plant on which Dehnhardt established E. camaldulensis and the plants now indicated by this name.
