Revised typification of the name Bupleurum gracile DC. var rollii Montel. (Apiaceae) and comparison with B. asperuloides Heldr., B. gracile D'Urv., B. marschallianum C. A. Mey and B. uechtritzianum S. Stoyanov.

Bupleurum gracile(M. Bieb.) DC. var.rolliiMontel. ( ≡ Bupleurum rollii[Montel.] Moraldo) is lectotypified on a herbarium specimen kept in RO, revising the previous typification by S. Snogerup and B. Snogerup. An isolectotypes and 14 syntypes are also selected. Infraspecific variability and comparison with related Eastern speciesB. asperuloidesHeldr.B. uechtritzianumS. Stoyanov andB. marschallianumC. A. Mey plusB. gracileD'Urv. are studied using morphometric and anatomical data. Notes on the ecology and distribution of the Italian endemictaxonare also provided.
