The name , described from Bosnia and Herzegovina, is lectotypified, and its taxonomic value is discussed. is currently considered an endemic subspecies common to Mallorca (Balearic Islands) and Bosnia and Herzegovina from the Balkan Peninsula. Specimens identified as from both Balearic Islands and Bosnia and Herzegovina were studied to determine if they are indeed the same taxonomic entity. Detailed micromorphological observations and morphometric analysis, suggest that the Balkan plants () and the Majorcan populations () are clearly separate entities. For the former name, based on morphological, phytochemical, biogeographical and present results, we propose the subspecific rank, as comb. & stat. nov. Full descriptions of all five subspecies currently accepted within are provided
