Enio Nardi’s scientific contributions

A taxonomic revision of the Italian species of Aristolochia L. has been carried out. Evidence and information were drawn from the study of living plants and herbarium exsiccata, including type material. The attention was focused on the flower morphological characters, frequently disregarded, and on the chromosome numbers. This resulted in the systematic, nomenclatural and chorological rearrangement of the genus with special regard to Italy. Ten taxa were recognized to grow in Italy against the seven or eight entities listed in recent Floras: A. altissima Desf. (Sicily); A. clematitis L. (continental Italy, Sicily); A, rotunda L. (mainland Italy, Tuscan Archipelago, Ischia, Sicily); A. insularis Nardi et Arrigoni (Sardinia); A. clusii Lojacono (S-Italy, Sicily); A. navicularis Nardi, sp. nov. (Sardinia, Egadi Is.); A. pallida Willd. (continental Italy); A. lutea Desf. (mainland Italy, Tuscan Archipelago, Sicily); A. tyrrhena Nardi et Arrigoni (Sardinia); A. sicula Tineo (Sicily). A. pistobchia L. is definitely excluded from the Italian flora. Each taxon is accompanied by a description, drawings from living and dried material, distribution maps, nomenclatural and systematic notes with special regard to the allied species growing in the Mediterranean area. A. pallida Willd. var. ehngpta Duchartre, from Greece, is treated as a selfstanding species under the name A. elongate (Duchartre) Nardi, stat. nov.
